Since the World Health Organization has clearly put forward the “three early” strategies for early detection, early diagnosis, and early treatment of cancer, cancer screening and early diagnosis and early treatment have been recognized as the most effective ways for cancer prevention and control. According to the statistics released by the National Cancer Center, in 2015, the incidence of malignant tumors in my country was about 3.929 million, and the deaths were about 2.338 million. On average, more than 10,000 people are diagnosed with cancer every day, and 7.5 people are diagnosed with cancer every minute. In the past 10 years, the incidence of malignant tumors has maintained an annual growth rate of about 3.9%, and the mortality rate has maintained an annual growth rate of 2.5%. The Anti-Cancer Association and the Cancer Hospital Affiliated to Fudan University launched the 2019 version of “Recommendation for Screening and Prevention of Common Malignant Tumors of Residents”, which expanded the knowledge of cancer prevention and treatment from 7 tumors in 2018 to 14. The “recommendation” adds thyroid cancer, lymphoma, esophageal cancer, and skin cancer to the original seven common male and female malignant tumors of lung cancer, colorectal cancer, liver cancer, stomach cancer, breast cancer, cervical cancer, and prostate cancer. , Pancreatic cancer, gallbladder cancer and brain tumor prevention and early diagnosis and treatment of authoritative popular science information, the tumor list has been expanded to 14. Popular science information for each cancer type includes: high-risk subjects, screening recommendations, and prevention recommendations. High-risk subjects with colorectal cancer: People with anorectal symptoms over two weeks of age over 1.40; 2. Immediate relatives with a family history of colorectal cancer; 3. People after treatment of colorectal adenoma; 4. Patients with chronic ulcerative colitis; 5. Population after surgery for colorectal cancer; 6. Immediate relatives over 20 years old with a family history of familial adenomatous polyposis (FAP) and hereditary nonpolyposis colorectal cancer (HNPCC); asymptomatic people over 7.45 years old. Note: Two-week anorectal symptoms refer to any of the following symptoms lasting more than two weeks: change in bowel habits (constipation, diarrhea, etc.); change in stool shape (thin stool thinning); change in the nature of stool (blood stool, mucus stool, etc.); pain in the abdominal fixed area . The screening recommendation recommends that the symptomatic high-risk subjects over 1.40 years old, who have no symptomatic relief after two weeks of symptomatic treatment, should be promptly examined by anorectal digital examination and stool occult blood test (FOBT), and any index should be positive for colonoscopy, such as FOBT The patient did not show any abnormality after enteroscopy. It is recommended to perform gastroscopy to rule out upper gastrointestinal bleeding. 2. Asymptomatic high-risk subjects over 40 years of age, receive a FOBT test once a year, if the occult blood test is positive, then further enteroscopy to confirm the diagnosis. If the FOBT test is negative for 3 consecutive times, the screening interval can be extended appropriately, but it should not exceed 3 years. 3. FAP and HNPCC family members older than 20 years old, when the first case of gene mutation in the family is clear, it is recommended to conduct genetic mutation testing, and positive people should have colonoscopy every 1-2 years. If the genetic mutation test is negative, screening is performed according to individuals over 40 years of age. 4.45-75-year-old asymptomatic screening subjects will receive FOBT examination once a year and enteroscopy every 10 years. 5. Multi-target genetic testing of feces or blood may be helpful for screening. Evidence of fecal specimens is more sufficient, but their price is limited, which limits their application. Prevention suggestions 1. Exercise can effectively reduce the occurrence of tumors, adhere to physical exercise to avoid obesity; 2. Healthy diet, increase the intake of crude fiber and fresh fruits, avoid high-fat and high-protein diet; 3. Non-steroidal anti-inflammatory analgesics may Effective for preventing bowel cancer, the elderly can try to take low-dose aspirin, which may reduce the risk of cardiovascular and cerebrovascular diseases and bowel cancer. Specific use must consult a doctor; 4. Quit smoking to avoid long-term toxicity and inflammatory irritation to the digestive tract . High-risk breast cancer subjects 1. Not having children, or primipara 35 years old; 2. Women with menarche ≤ 12 years old, or menstrual period ≥ 42 years old; 3. First-degree relatives with breast cancer before 50 years old; 4. More than two Those with first- or second-degree relatives who had breast or ovarian cancer before the age of 50; 5. History of contralateral breast cancer, or severe atypical hyperplasia or intraductal papilloma confirmed by breast biopsy; 6. Chest radiotherapy History (≥10 years). Note: First-degree relatives refer to parents and children. First-level siblings (same parents). Second-degree relatives refer to uncles, uncles, aunts, uncles, aunts, grandparents, and grandparents. The above-mentioned conditions are all high-risk factors for breast cancer. When two or more factors are involved, they should be considered as high-risk breast cancer subjects. Screening recommendations 1. Self-examination of the general breast of women: check once a month after the age of 20
The reason why cancer is so powerful lies in the stealth function of cancer cells. Just like a fighter, the better the stealth performance, the lower the chance of being discovered by the enemy, and the greater the lethality. The stealth function of cancer cells is specifically expressed in two aspects! One is that the cancer has already occurred due to stealth function or concealment, and the human body can’t feel it, or there is no abnormal discomfort. As it grows, grows, or moves away, it slowly makes people feel it. Existence, the direct consequence of this situation is “a discovery is late”! For humans with advanced cancer who still cannot crack its codons, various dazzling treatments can only be exhausted until the end of life. The second is drug resistance. Everyone knows that some cancers, when they first started using a certain drug, the effect is very good, and the tumor shrinks soon, but it won’t be long before you are using the same kind of drug, it is useless because the cancer The cell is “invisible”, and its invisibility makes it difficult for drugs to attack it. This is called drug resistance. Although the stealth function of cancer cells has caused serious consequences such as the difficulty of early detection of cancer, the difficulty of long-term effective treatment, and the high mortality rate, should humans be able to catch it? Obviously not. First of all, our body often has many early warnings in the early stages of cancer, such as bowel cancer. Some patients with bowel cancer may have a slight change in bowel habits at the beginning. For example, the original stool is dry, it suddenly becomes thinner, and some of the original stools are thicker and later become very thin. , Some of them used to defecate once a day, and later became two to three times a day, or some became twice a day, and then became once every three to four days. These details will also show up in different gastroenteritis, so they will often be People ignore it, and the time is longer, the problem is not easy to deal with. Therefore, we must fully understand the basic characteristics of our body, and pay more attention to the inexplicable details to solve the problem. Another consequence of cancer cell stealth is drug resistance. Scientists are also trying to find the mechanism and solution of drug resistance. I believe that in the near future, people may see treatment measures for drug resistance.
Farting is an embarrassing thing everyone has had. Occasional farting is physiological and harmless. However, excessive farting is not necessarily a trivial matter! 27-year-old Xiao Min (pseudonym) is a company white-collar worker. Recently, no matter what she eats, she always has a lot of farts, especially in the elevator, which makes her very embarrassed. Recently, she found that in addition to fart, she often has diarrhea and abdominal pain, but she thought that she was eating too spicy, which caused gastrointestinal discomfort and she didn’t care. After her parents discovered Xiaomin’s anomaly, she immediately asked her to go to the hospital. After colonoscopy and CT, pathological results showed: stage III bowel cancer. How is the “fat” in the body produced? When we eat and drink, we will swallow a lot of air unconsciously. There are generally two ways to expel this air: one is burping, and the second is farting. After the air enters the stomach, it can stimulate the plexus nerve and the phrenic nerve of the stomach, causing hiccups and expelling the air from the stomach. But hiccups can only expel a part of the gas, and the other part stays and accumulates in the stomach.  . Another part of the gas enters the intestine, forming intestinal gas. Our fart is this part of intestinal gas. What is the relationship between fart and bowel cancer? In fact, there is no research to confirm that there is a close relationship between fart and bowel cancer. But it is worth noting that in certain cases of bowel cancer can indeed lead to increased fart production. For such people with colorectal cancer, one of the symptoms is frequent farting, but in addition to this symptom, the patient will also show abdominal pain and obvious weight loss. The shape of the stool and the regularity of bowel movement will have an impact. It needs a comprehensive reason. Can consider whether it is colorectal cancer. If a person just increases the number of farts, and the body does not have other abnormal reactions, then generally it is not caused by colorectal cancer. However, if accompanied by the symptoms mentioned below, then be careful of bowel cancer. These are also the signs of bowel cancer. Bowel cancer is a typical “rich disease”, which is related to people’s living conditions and diet. Li Wenxia, an oncologist at Beijing Shijitan Hospital affiliated to Capital Medical University, pointed out that if the following five “signs” (including some abnormalities in stool), the possibility of colorectal cancer should be considered: 1 change in bowel habits early diarrhea, constipation or Diarrhea alternates with constipation.  . There are also some people who show increased stool frequency, frequent bowel movements, and urgency. In addition, stools will also appear deformed and thinned. 2 Bloody stools are mainly caused by tumor ulceration. The bloody stools are dark red, mucus discharges, or smelly pus bloody stools. 3 Anemia tumor growth requires a lot of blood supply, so as the tumor gradually grows, patients may have varying degrees of anemia. In addition, blood in the stool can also cause anemia. 4. Abdominal pain, abdominal distension and discomfort The tumor continues to grow, and some patients will experience abdominal distension and discomfort. 5 The right colon of the abdominal mass is anatomically characterized by a large cavity and a thin wall. The contents of the intestinal cavity are mostly liquid, and the tumor can grow into the intestinal cavity. 60% to 70% of patients in the middle and late stages can reach the right mid-abdomen A hard mass, which is a sign of colon cancer on the right. Intestinal cancer has almost no symptoms in the early stage, and some may be abdominal discomfort or bloating, which is why many people do not care. Some patients mistakenly thought hemorrhoids because of bloody stool symptoms, which delayed treatment. It is recommended that everyone should pay attention to the screening of intestinal cancer, and healthy people over the age of 45 should be checked for fecal occult blood annually. These two kinds of stinky, let the intestinal cancer expose a stinky as soon as possible, it is almost embarrassing to die. The smelly fart can be caused by more fecal retention in the intestine that is not discharged in time. Most of the gas that causes stinks is generated by the decomposition of protein food ingredients that have not been absorbed in time. 1 rotten egg-flavored fart rotten egg-flavored fart is equivalent to protein metabolism to the last spoiled taste, at this time the gastrointestinal tract may be problematic. Therefore, stinking farts is not only an embarrassing thing, but also a red flag. 2 Fishy fart Bloody smell fart, which indicates bleeding in the digestive tract. Blood accumulates in the patient’s gastrointestinal tract. Stomach acids and intestinal bacteria break down the blood. Sometimes the excrement will be like tar, and the fart will have a fishy smell. When there is a malignant tumor in the intestine, the fart also smells due to the erosion, flaking, and bleeding of cancer tissues, plus the decomposition and fermentation of bacteria. Therefore, the stool color is black, or the smelly fart must go to the hospital for examination. Anti-intestinal cancer, dietary recommendations so that the current number of patients with intestinal cancer in my country is increasing year by year
Tumor does not want to amputate? Are there any other treatment options? Recently, the editor interviewed Dr. Li Dingfeng, the former Cancer Hospital of the Chinese Academy of Medical Sciences. He pointed out that subcutaneously implanted arterial chemotherapy can increase the concentration of chemotherapy drugs, reduce toxic and side effects, and provide the possibility for tumor patients to preserve organs, limbs and functions. Professor Li Dingfeng, the former expert of the Cancer Hospital of the Chinese Academy of Medical Sciences and the chief physician of the Cancer Center of Xiangya Boai Hospital, introduced that for solid tumors, the standard treatment mode of chemotherapy, surgery, and re-chemotherapy should be followed. Chemotherapy before surgery can effectively kill satellite foci around tumors and subclinical foci of distant metastasis. The primary foci of tumors can be reduced by chemotherapy, and clear surgical boundaries can create conditions for surgery. Preoperative neoadjuvant chemotherapy: the primary focus can be reduced and the tumor boundary is clear, creating conditions for surgical operations. Subcutaneous implantable arterial chemotherapy technology provides the possibility of subcutaneous implantable arterial chemotherapy for organ preservation, limb preservation, and function preservation: will The chemotherapeutic device is buried under the skin near the tumor, and the drug delivery catheter is introduced into the artery that supplies blood to the tumor tissue. The size of this chemotherapeutic device is not large. After being buried in the human body, it has basically no effect on the normal activities of the person before and after the surgery for a long time. When the medicine needs to be administered, the medical staff can simply use a common syringe to push the medicine into the chemotherapeutic device. According to the condition, the medicine can be administered at any time or for a long time, which is simple and convenient. Because the chemotherapeutic drugs are produced by the chemotherapeutic device and reach the tumor tissue, the degradation of the liver and kidney before the tumor reaches the tumor is avoided, and the drug concentration in the tumor area is increased, and each time it is doubled, the therapeutic effect can be increased by 10-20 times. In this way, not only can the drug effect be fully exerted, but also the toxic side effects of the drug on the human body are reduced. Then, in response to the problem of strong repair ability of tumor cells in the past, an anti-repair agent was administered through a chemotherapeutic device to inhibit the repair of tumor cells and further improve the killing effect of chemotherapy drugs on tumor cells. Another advantage of using this chemotherapy method is the short course of treatment. It is clinically proven that the effect of one course of chemotherapy is equivalent to the effect of 2-3 courses of ordinary chemotherapy. More importantly, in the process of applying this method, some soft tissue tumors that are not sensitive to traditional chemotherapy methods, such as liposarcoma, alveolar rhabdomyosarcoma, and synovial sarcoma, etc., can be completely treated by this method. Killing tumor cells is extremely beneficial for retaining patients’ limbs. Limb salvage treatment for osteosarcoma with obvious pathological fractures 29-year-old osteosarcoma with obvious pathological fractures Osteosarcoma with salvage pathology Treatment of skin dermal fibrosarcoma soft tissue sarcoma sarcoma and cancerous ulcers The technique of “subcutaneous implantable arterial guided chemotherapy” in the right forearm soft tissue deficiency group, due to the greatly increased drug concentration and duration of drug efficacy, enhances the treatment of tumor cells Killing effect, while increasing the repair agent caffeine after tumor chemotherapy, so it has obvious advantages in the treatment of bone and soft tissue tumors, such as pro-apoptosis, anti-repair, and maximum avoidance of amputation. In addition, it also has bone metastasis cancer, Primary tumors, such as pelvic malignant tumors, lung cancer, breast cancer, prostate cancer, and gastric cancer, can play a better therapeutic role, and have formed a mature technology with a wide range of treatments.
Neuroblastoma is the most common malignant (cancerous) extracranial solid tumor in childhood. It develops from the tissue that forms the sympathetic nervous system, which is part of the nervous system that regulates involuntary body functions. Tumors usually start from the nerve tissue of the adrenal glands (above the kidneys), but may also start from the nerve tissue of the neck, chest, or pelvis. Although neuroblastoma usually exists at birth, it is usually not discovered until the tumor begins to grow and compress surrounding organs. Cancer cells can quickly metastasize (spread) to other parts of the body, such as lymph nodes, liver, lungs, bones, central nervous system, and bone marrow. Nearly 70% of children diagnosed with neuroblastoma will have metastatic disease. In children under the age of 15, 10.54 cases of neuroblastoma occur every 1 million children every year. About 37% of patients are diagnosed during infancy (<. 1 year old), and 90% of patients are younger than 5 years old. The average age of onset is 19 months. According to the World Health Organization report, childhood cancer is relatively rare, and childhood cancer patients only account for 0.5% to 4.6% of the total number of cancer patients. Cystic adrenal masses were identified by non-contrast fetal MRI at 36 weeks and 2 days of pregnancy. The white arrow points to the 3.1×3×2.8 cm lesion of the left adrenal gland. First, the signs and symptoms of the disease neuroblastoma depend on which part of the body is affected. 1. Symptoms and signs of abdominal neuroblastoma A, abdominal pain, B, hard abdominal C, changes in bowel habits, such as diarrhea or constipation 2, symptoms and signs of chest neuroblastoma A, wheezing B, chest pain C, eyes Changes include drooping eyelids and uneven pupil size3, other signs and symptoms of neuroblastoma A, subcutaneous tissue mass B, protruding eyeball C, dark circles around the eye similar to bruise D, back pain E, fever F , Unexplained weight loss G, bone pain three: the reason is usually that cancer starts with gene mutations, cancer cells grow and reproduce uncontrollably, and the abnormal cells that gather form clumps (tumors). Neuroblastoma begins with neuroblasts, immature nerve cells produced by the fetus during development. As the fetus matures, neuroblasts will eventually become nerve cells and fibers and the cells that make up the adrenal glands. Most neuroblasts will mature at birth, although a small amount of immature neuroblasts will be found in newborns. In most cases, these neuroblasts mature or disappear. However, others form tumors-neuroblastoma. Most neuroblastoma cells have abnormalities involving specific chromosomes (chromosome 1), and more malignant tumors usually have multiple copies of the oncogene MYCN in tumor cells, but there may also be many other genetic abnormalities. Four: Risk factors Children with a family history of neuroblastoma are more likely to suffer from this disease. Five: Complication 1, cancer spread (metastasis), neuroblastoma may spread (metastasize) to other parts of the body, such as lymph nodes, bone marrow, liver, skin and bones. 2. The spinal cord is compressed, and the tumor may grow and press on the spinal cord, causing the spinal cord to be compressed. Compression of the spinal cord may cause pain and paralysis. 3. Signs and symptoms caused by tumor secretions. Neuroblastoma cells may secrete certain chemicals, which will stimulate other normal tissues and cause signs and symptoms called paraneoplastic syndrome. A paraneoplastic syndrome that rarely occurs in patients with neuroblastoma can cause rapid eye movement and coordination difficulties. Another rare syndrome causes swelling of the abdomen and diarrhea. Six: Diagnosis 1, urine and blood tests, urine tests can be used to check certain chemicals caused by excessive production of catecholamines by neuroblastoma cells. 2. Sample test, imaging examination can show a tumor mass. Imaging tests can include X-rays, ultrasound, computed tomography (CT) scans, inter-iodobenzylguanidine (MIBG) scans, and magnetic resonance imaging (MRI), etc.3. Biopsy, if a mass is found, the doctor may wish to take out a tissue sample to perform Laboratory examination. Special testing of tissue samples can reveal which types of cells are involved in the tumor and the specific genetic characteristics of cancer cells4. Take a bone marrow sample for testing to see if the neuroblastoma has spread to the bone marrow-the spongy shape inside the largest bone that forms blood cells substance. To remove the bone marrow for testing, insert a needle into the body
Prostatitis, benign prostatic hyperplasia, and prostate cancer. For these kinds of prostate diseases, boys are familiar with them, and they are more or less familiar, but what is the “prostate calcification focus”? Will it become cancerous? One: Why does the prostate calcify? “Prostate calcification foci”, also known as prostate calcification, is not a separate disease. It is the presence of calcium deposits in the prostate seen by ultrasound, X-ray or CT imaging. The formation of prostate calcification is actually similar to the formation of urinary tract stones. The prostate has glandular ducts. Urine or secretions in the glandular ducts may remain to form crystalline calcification, just like the silt in the river channel. It will slowly become clumped and hardened over time. The calcification of the prostate, in addition to the deposition of substances in the prostate gland duct, also refers to the scars left after the local lesions have been cured, just like the scars on the bark. It was previously injured, but now it is good and leaves scars. The cause of prostate calcification is still unclear. Existing research believes that it may be related to factors such as chronic prostatitis, retention of prostate fluid, degeneration of prostate tissue, stenosis of the prostate tube, disturbance of calcium and phosphorus metabolism, and frequent prostate hyperemia. The most common cause of prostate calcification is prostatitis or prostate stones, which leads to calcifications on imaging. When urinating, urine flows back into the prostate gland duct. Over time, the components in the urine precipitate and crystallize. On the other hand, urine reflux stimulates the prostate to cause inflammation, and after repeated inflammatory stimulations, prostatitis will heal scars, which are calcified spots, after healing. This is like the calcification point formed after the tuberculosis has healed. The unhealthy lifestyle leads to an increasing incidence of prostatitis. For young men in their twenties or thirties, physical examination reveals calcification of the prostate, which may mean suffering from prostatitis, at least once. But over 50 years old, benign prostatic hyperplasia with ageing can also cause calcification in the prostate. Calcification itself does not cause any symptoms. However, calcification of the prostate can block the prostate gland ducts, prone to breed bacteria, and may cause treatment of prostatitis and repeated attacks. Therefore, patients with prostatitis are prone to develop calcification of the prostate; patients with prostate calcification are also prone to induce prostatitis. Two: Why is the calcification of the prostate cancerous? Prostate cancer ranks first among male malignancies in developed countries in Europe and America. The latest cancer data released by the National Cancer Center of my country shows that prostate cancer has gradually increased with the degree of urbanization, and the incidence of prostate cancer in Beijing, Shanghai and Guangzhou is close to that of European countries. What is more worrying is that more than 70% of prostate cancer patients are already in the advanced stage when they are first diagnosed. Under the influence of this anxiety atmosphere of “talking about cancer color change”, many male friends worry that prostate calcification will become cancerous. Prostate calcification is mainly closely related to prostatitis and has no clear direct relationship with prostate cancer. Calcification of the prostate is neither precancerous nor directly malignant. Three: How to treat prostate calcification? Prostate calcification will not disappear by itself. Prostate calcification unintentionally found in health examinations or other examinations has no uncomfortable symptoms and generally does not require treatment. Only need to pay attention to the health of the genitals in daily life, and regularly review. Men over 45 years old, it is necessary to do blood PSA (prostate specific antigen) examination, finger finger examination, and prostate ultrasound examination once a year. For prostatitis caused by calcification of the prostate, patients with frequent urination, urgency, dysuria and other symptoms, the need for standardized treatment of prostatitis. The specific treatment method for prostatitis should be based on whether there are pathogen infection and inflammation type, choose to take appropriate drugs, and combined with prostate massage, hyperthermia, biofeedback and other comprehensive treatment. If prostate calcification is accompanied by symptoms such as hematuria and difficulty in urinating, do not use medication on your own. You should go to the urology department of a regular hospital in time to pass PSA prostate specific antigen, prostate CT, MR and other tests to rule out whether there are prostate hyperplasia, prostate tumor, prostate Tuberculosis and other diseases. For boys with prostate calcification, pay attention to the following points in daily life: 1. Improve learning ability, obtain correct health science knowledge, and do not superstitious advertisements; 2. The best smoking habit is to quit smoking, and alcohol should also be controlled; 3. Diet Balanced nutrition, eat more fresh fruits and vegetables, and eat less spicy, stimulating food; 4. When summer comes, pay attention to drink plenty of water, do not hold back urine; 5, combine work and rest, avoid overwork, try to stay as low as possible
. . Liu Jie (pseudonym), who came to Urumqi, Xinjiang, suddenly found that her lower body was bleeding irregularly in July 19, but did not attract attention and did not do anything. In August, when the situation was serious, I thought of going to the hospital for examination.  . . Sister Liu (pseudonym), who hadn’t taken her seriously, was taken seriously when she received the hospital’s examination report, and she was out of breath with cervical cancer. The treatment plan given by the hospital can only be done by radiotherapy and chemotherapy, and there is no way to take surgical treatment, otherwise it can only go to the higher level hospital.  . .Liu (pseudonym) was originally weak, and the people in her family decided not to take radiochemotherapy after consultation, fearing her body would not be able to persevere. Sister Liu (pseudonym) September’s Pat CT . . After many inquiries, I finally learned from a friend’s relative that Professor Yao Bo’s precise three-dimensional overall tumor elimination method, and the relative’s family after treatment is very good Although she was skeptical at the time, there was no way for Liu’s (pseudonym) to continue to drag on. Finally, Sister Liu (pseudonym)’s husband decided to go to Changhe Taihe Hospital first.  . . When I came to the hospital at that time, in the words of Sister Liu (pseudonym), “My husband was very cold when he came. I felt like this hospital could treat such a serious disease. I decided to go back now”, But Sister Liu decided that since she had come, she would take a look first and find other patients to understand the treatment effect.  . . After some understanding and communication with other patients, Liu Jie (pseudonym) said, “Since other people have such good results, why can’t I treat it?” During the rounds, the tumor has basically been completely eliminated after receiving a period of treatment. Liu Jie (pseudonym) said that this treatment is simply too good, and she is not at all guilty. The radiochemotherapy patients seen in the hospital are completely different, and the whole treatment is very easy. Sister Liu (pseudonym) Pat CT
In Europe and the United States, more than 70% of cancer patients receive radiotherapy at different stages of treatment, and about 40% of cancers can be cured by radiotherapy; while in China, only 20% to 30% of cancer patients choose to receive radiation therapy. With the development of modern radiotherapy technology, put on therapy plays an increasingly role of providing technology in tumor treatment. Many early cancer radiotherapy can achieve the same results as surgery, especially in the United States. We can foresee that soon radiotherapy doctors can become the first doctors of patients like surgeons. Although my country’s radiotherapy has developed rapidly in recent years, it is still relatively low compared to Japan and the United States as a whole, and the consistency of radiotherapy quality between different hospitals is also very large. 1. Radiotherapy equipment of different grades of hospitals differs greatly. According to the US NCCN standard, the basic requirement of radiotherapy is three-dimensional conformal radiotherapy. However, about 30% of radiotherapy equipment in China is outdated and can only be used in two dimensions. Radiotherapy. Of course, more than 70% of the radiotherapy equipment in my country can carry out the most basic three-dimensional conformal radiotherapy, but most accelerators cannot carry out the advanced photon radiotherapy technology SBRT stereotactic radiotherapy, which naturally limits the development of advanced radiotherapy technology. The tumor site that can be used for SBRT, the local control rate and toxic side effects of the tumor are far stronger than the general three-dimensional conformation, and the three-dimensional conformation is stronger than the two-dimensional. In addition to the doctor’s technology, the accelerator equipment is required to carry out Yes, so the difference in the accelerator itself will greatly affect the quality of radiotherapy treatment. 2. The effects of different levels of hospital radiotherapy are different. Radiotherapy and surgery are also a craft job! ! The overall development level of the subject of radiotherapy is relatively low in my country, and it has been carried out relatively late in my country in terms of oncology surgery and oncology. This leads to a relatively poor quality of the entire subject compared to surgery. Radiation therapy has not been carried out in many places so far. Radiotherapy physicists are few and far between, and physicists with rich experience in radiotherapy are even rare. The relationship between a radiotherapy physician and a radiotherapy physicist is like a relationship between a surgeon and an anesthesiologist. Good anesthesia is the prerequisite for the smooth operation of the operation, and physics is the guarantee for the successful implementation of the radiotherapy plan. The two are responsible for each other, but complement each other and are indispensable. The key role of physicists in radiotherapy: to ensure the effectiveness, safety and maneuverability of radiotherapy plans. WHO’s recommendation is to provide 2-3 accelerators per million population on average. In the 2016 survey, my country only had 1.4 accelerators per million people. Oncology now respects multidisciplinary joint diagnosis and treatment, but there are not many large hospitals that can truly achieve multidisciplinary consultation. Cancer patients are basically surgery-based. In internal medicine, Chinese patients are willing to take medicine and injections. What the hell is radiotherapy? In the end, what determines the quality difference of patients receiving radiotherapy? The difference in the quality of radiotherapy depends on the level of the radiotherapy team 80% and the equipment 20%. A perfect operation is closely related to a surgeon with rich clinical experience. However, for a perfect radiotherapy plan, in addition to requiring experienced doctors and physicists, high-tech radiotherapy equipment is an important prerequisite. It is no exaggeration to say that the equipment also determines the level of radiotherapy in the hospital. It is recommended that you find a top three large hospital when you are looking for a radiotherapy hospital, a hospital with a professional radiotherapy department or a multidisciplinary diagnosis and treatment.
1. What is hyperthermia? Hyperthermia is a cancer treatment method. Studies have shown that high temperature can damage and kill cancer cells with minimal damage to normal tissues. Hyperthermia may shrink the tumor by killing the cancer cells and destroying the proteins and structures in the cancer cells. 2. How is hyperthermia used to treat cancer? In clinical practice, hyperthermia is always used to treat cancer together with radiotherapy and chemotherapy. After thermotherapy, radiotherapy will make cancer cells more sensitive to radiation. When hyperthermia and radiation therapy are used in combination, the effect of killing stubborn cancer cells is more effective. The combination of chemotherapy can also enhance the role of anticancer drugs. Many clinical trials have studied hyperthermia combining radiation therapy with chemotherapy. These are focused on the treatment of multiple cancer types. Including sarcoma, melanoma, head and neck cancer, brain cancer, lung cancer, esophageal cancer, breast cancer, bladder cancer, rectal cancer, liver cancer, cervical cancer, peritoneal cancer, etc. In these studies, hyperthermia combined with radiochemotherapy was shown. The tumor area is significantly reduced, and the treatment effect is extremely significant. 3. What are the different methods of hyperthermia? 1) In local hyperthermia, the technique of heating the tumor applies heat to a small area of the tumor. Different types of energy can be used to apply heat, including microwave, radio frequency, and ultrasound. Depending on the location of the tumor, there are several methods for treating local hyperthermia: A, . External methods are used to treat tumors in or under the skin. The external applicator is located around or near the appropriate area, and energy is concentrated on the tumor to increase its temperature. B, . The intraluminal method can be used to treat tumors in or near the body cavity, such as the esophagus or rectum. The probe is placed inside the cavity and inserted into the tumor to transfer energy and directly heat the area. C, . Interstitial technology is used to treat deep tumors in the body, such as brain tumors. This technique allows the tumor to be heated to a higher temperature than external techniques. Under anesthesia, insert the probe or needle into the tumor. Imaging techniques such as ultrasound can be used to ensure that the probe is correctly positioned within the tumor. Then insert the heat source into the probe. Radio frequency ablation (RFA) is an interstitial fever that uses radio waves to heat and kill cancer cells. 2) . In local hyperthermia, hyperthermia can heat a large area of tissue, such as body cavity, organs or limbs. A, deep tissue method can be used to treat cancer in the body, such as cervical cancer or bladder cancer. An external applicator is placed around the body cavity or organ to be treated, and microwave or radio frequency energy is concentrated in this area to increase its temperature. B. The regional perfusion technique can be used to treat cancers of the arms and legs such as melanoma or cancers of certain organs such as liver or lungs. During this process, some of the patient’s blood is removed, heated, and then pumped back to the limb or organ. Anti-cancer drugs are usually given during this treatment. C. Continuous high temperature peritoneal perfusion (CHPP) is a technique used to treat cancer in the peritoneal cavity (the space containing the intestine, stomach, and liver in the abdominal cavity), including primary peritoneal mesothelioma and gastric cancer. During the procedure, heated anticancer drugs flow from the heating device through the peritoneal cavity. The temperature of the peritoneal cavity reaches 40cº-42cº. 3) . Whole body hyperthermia is used to treat metastatic cancer that has spread to the whole body. The technology to increase the body temperature to 40cº-42cº. National Center for Bioinformatics: Data analysis of 22 patients with advanced cervical cancer in Rotterdam treated by radiotherapy + hyperthermia + chemotherapy: all 22 patients with locally advanced cervical cancer (104 types) who participated in the three-mode treatment feasibility study were selected Hyperthermia method). The patient underwent high-voltage external beam radiation therapy to the pelvis at a daily dose of 2Gy every Friday for a total dose of 46Gy, and received additional brachytherapy, at least four cycles of cisplatin (40mgm-2) and five The second course of treatment uses BSD2000-3D and Sigma60 or Sigma-eye applicator at a frequency of 70-120MHz for local local deep hyperthermia every week. For each single treatment, the RHyThM tissue type was defined along the insertion length according to the CT scan information of the radiotherapy position. A step change in the slope of the profile of the first temperature map is identified to verify the precise length of the insertion of the temperature measurement catheter and the transition between in vivo and in vitro. Perform data analysis based on temperature readings provided by RHyThM. Results: The temperature and RF power data of 97 treatments can be analyzed. The intravaginal temperature index is slightly lower
As one of the three major means of cancer treatment, therapy has a very important position in the treatment of cancer. But due to the side effects caused by chemotherapy, many patients are discouraged and even very scared. For these side effects, it is also very important to take corresponding measures, every cancer chemotherapy patient and family members need to know. ▲The nausea and vomiting caused by the treatment will greatly reduce the patient’s quality of life. 1. Bone marrow suppression 1. Leukocyte suppression: WBC decline begins more than a week after stopping the drug and reaches the lowest point at about 10, maintaining at a low level for 2 to 3 days. That is, it starts to pick up, and it can return to normal after 7 to 10 days. In general, I and II degree white blood cell suppression does not need to be treated, and most can be recovered naturally, and will not affect the next course of chemotherapy. Usually, III and IV degree white blood cell suppression requires active treatment. 2. Platelet inhibition: Platelets fall later than white blood cells, but they rebound very quickly. There are currently no very good drugs to treat platelet decline. No treatment is required for platelet inhibition of degree I and II, and active treatment is required for platelet inhibition of degree III and IV. 2. Digestive tract symptoms 1. Treatment of nausea and vomiting Last week, the American Society of Clinical Oncology (ASCO) updated the medication recommendations for antiemetic programs to prevent and treat nausea and vomiting caused by chemotherapy. In order to ensure the authority and practicality of the content, the expert team includes oncologists, radiologists, nurses, pharmacists, medical service research experts and patient representatives. The expert group conducted a systematic review of the medical literature published between 2009 and 2016, and finally developed this guideline. The main contents of the guideline are: after receiving chemotherapy (such as the combination of cisplatin, cyclophosphamide and anthracycline) Adult patients with a higher risk of nausea and vomiting should add olanzapine to the standard antiemetic regimen (usually a combination of 5-HT3 receptor antagonist, NK1 receptor antagonist and dexamethasone). Olanzapine can also help Patients should prevent vomiting before the start of chemotherapy. Adult patients receiving carboplatin-based chemotherapy or high-dose chemotherapy, as well as pediatric patients who are at higher risk of nausea and vomiting during chemotherapy, should add NK1 receptor antagonists to the standard antiemetic regimen ( 5-HT3 receptor antagonist and dexamethasone combination). In patients receiving a combination of anthracyclines and cyclophosphamide, dexamethasone can be used only on the day of chemotherapy. Patients with standard antiemetic programs do not work, experts The team recommends the use of FDA approved cannabinoids, dronabinol or nabilone, to treat nausea and vomiting. However, there is insufficient evidence to prove the use of medical marijuana to treat nausea and vomiting associated with radiochemotherapy. 2. Diarrhea can be given live bacteria preparations to increase the number of negative bacilli in the intestine, such as intestinal growth. When highly suspected of pseudomembranous enteritis, do not give antidiarrheal drugs, which will increase the symptoms of intestinal poisoning. 3. Constipation eat more vegetables, water, high fiber diet. Open Serena anal. 3. Oral ulcers Oral ulcers are a manifestation of gastrointestinal ulcers, indicating that ulcers have also occurred in other parts of the digestive tract. The drug began to appear after 5 to 6 days, and gradually healed until about a week after the drug was stopped. Ulcers caused by antimetabolites mostly occur in the lip and cheek mucosa. In severe cases, it can extend to the pharynx, esophagus and even anus, and a few can spread to the vagina and urethra. The ulcers caused by repromycin are mostly on the tongue side and the base of the tongue, and the ulcers are deep and painful. Oral care: high pressure physiological saline is used to rinse the ulcer part, remove the surface secretions and necrotic tissue, and apply the medicine locally. More talk is conducive to the healing of ulcers. Pay attention to changes in body temperature. Pay attention to the deterioration of local infections and become the basis of systemic infections. Apply antibiotics in time, especially some antibiotics against anaerobic infections. 4. Once drug extravasation occurs, the drug will be partially closed: Procaine + normal saline / Procaine + normal saline + dexamethasone / ice pack. 5. Hair loss Hair loss is the most common side effect during chemotherapy. In 2015, a cooling device called DigniCap was approved by the FDA for the treatment of breast cancer in women. Recently, two articles published in “Journal of the American Medical Association” pointed out that this device has a significant effect. The results showed that the hair loss of female patients using the device was relieved by 50%. More important to the patient is the heart
. Malignant tumors are one of the serious diseases that endanger human health. The incidence of cancer has been increasing in recent years. Although the level of tumor diagnosis technology has been greatly developed, the treatment mainly relies on surgery, radiotherapy, and chemotherapy. These methods have certain limitations. With the rapid development of contemporary science and technology, people have made remarkable achievements in the research of tumor hyperthermia in the past 20 years, and played an important role in the comprehensive treatment of tumors. Tumor hyperthermia has become the fifth largest therapy after surgery, radiotherapy, chemotherapy and immunotherapy, and is a new effective method for treating tumors.  . Tumor hyperthermia can not only treat tumors alone, but also organically complement hyperthermia with chemotherapy, radiotherapy, Chinese medicine treatment, etc., and increase the sensitivity of patients to chemotherapy, radiotherapy, Chinese medicine. It can more effectively kill malignant tumor cells, improve the quality of life of patients, prolong the lives of patients, and at the same time reduce the side effects of radiotherapy and chemotherapy, so it is called “green therapy” by the international medical community.  . . The principle of hyperthermia is to use a physical method to heat the tissue to a temperature that can kill the tumor cells (40℃-43.5℃) for 40 to 60 minutes, so as not to damage normal tissue (normal tissue cells The temperature safety limit is 45℃±1℃) and the method destroys tumor cells. Hyperthermia not only has a direct cytotoxic effect on tumor cells, but also enhances the efficacy of chemotherapy and radiotherapy, improves the body’s immunity, and inhibits tumor metastasis.  . Due to the distorted blood vessels in tumor tissue, large blood flow resistance, unsound vascular receptors, poor sensitivity to temperature, it is difficult to dissipate heat under high temperature, the heat is easy to focus, and the temperature rises quickly, forming a huge heat storage reservoir, which can be used with normal tissues There is a temperature difference of 5 ~ 10 ℃; and normal cells can tolerate high temperature of 40 ℃ ~ 43.5 ℃ for a long time, thereby killing tumor cells while normal cells are not affected, and will not cause adverse reactions such as bone marrow suppression and hair loss. This is the unique difference between hyperthermia and chemotherapy and radiotherapy. Moreover, hyperthermia is only pure “extractive” physical heat energy, which does not cause any harmful pollution to people and the environment. Therefore, it is a green treatment, and is even hailed by foreign medical experts as a “sign of the arrival of medical spring.”  . Professor Li Dingfeng was invited to attend the 2019 National Hyperthermia Annual Conference . Currently, clinical hyperthermia mainly uses local hyperthermia. Some experimental studies have shown that local hyperthermia can not only directly kill tumor cells, but also increase the body’s immune function. The effect of degeneration and necrosis of the tumor after local high fever, the result of stimulating the body’s immune function by absorbing the necrotic tumor products. Combined hyperthermia and hyperthermia combined with chemotherapy, that is, thermochemotherapy, can increase the concentration of drugs in the tumor and enhance the anti-tumor effect; at the same time, it can reduce the toxic effect of chemotherapy drugs on unheated normal tissues; the combination of the two also helps Prevent and delay the emergence of drug resistance. In addition, the tumor cells located in the central part of the tumor are hypoxic and insensitive to radiation. They cannot be completely killed after radiotherapy, and often become the source of tumor recurrence. Hyperthermia is particularly powerful for this type of tumor cells; especially for radiotherapy Resisting S-phase cells are particularly vulnerable to high fever. Therefore, hyperthermia can make up for the shortcomings of radiotherapy, and combined use can improve the efficacy.
Yuanhu, alias Yanhusuo, Xuanhusuo. It is the tuber of the perennial herbaceous plant Yanhusuo of the poppy family. Mainly produced in Jiangsu and Zhejiang. The warm and humid sandy soil is an excellent environment for the growth of Yuanhu. Yuanhu is known as “the first medicine for pain relief of traditional Chinese medicine”. It is used not only for various benign diseases, such as gastrointestinal gastroenteritis and gastrointestinal pain, cholecystitis liver pain, but also for cancer pain caused by some tumor diseases. . Yuanhu tastes bitter, bitter, and warm. Guixin, liver and spleen. Efficacy: Focus on activating blood circulation, qi and relieve pain. “Compendium of Materia Medica” said: “Specially treat all kinds of pain in the body, the use of it is wonderful.” When taken in water, the general dose is 5-10g, and 1.5-3g is swallowed by grinding. Stir-fried Yuanhu in vinegar can strengthen the analgesic effect. Pain is a common comorbidity of tumor diseases, especially in 80% of advanced cancers. Pain occurs only in western medicine. Western medicine only has opioid drugs. Although these drugs have strong analgesic effects, they have many side effects. Yuanhu preparations such as vinegar fried Yuanhuyan can be used in early cancer Swallow at the end, or directly choose Chinese patent medicine Yuanhu Zhitong Dripping Pills, when combined with turmeric, whole scorpion, and azadirachta, the Chinese medicine compound can enhance the anti-cancer pain effect. It is especially used for cancer pain of gastric cancer, liver cancer, pancreatic head cancer, intestinal cancer and other tumors. Modern research has found that Yuanhu contains more than 10 alkaloids, among which the more important ones are Yanhusuo B, ugly and A. Stir-fried vinegar can greatly increase the concentration of alkaloids, and stir-fry the wine can cause some of the alkaloids to be destroyed and lost. In vitro experimental studies have obvious analgesic effect, the analgesic effect of powder is about 1/100 of opioids. Clinically, it is best to use powder and alcohol extract.
In August last year, sister Hu (pseudonym) inexplicably felt pain and discomfort in her neck and back. At first, I didn’t pay much attention to it. I thought I was too tired recently and didn’t have a good rest. Sister Hu (pseudonym) didn’t realize the seriousness of the problem until the situation became serious (no way to lie down).  . . The results of the examination in the local hospital show that breast cancer is advanced, and the bones of the cervical 2-thoracic 1 vertebral body and cervical 6 vertebral body are damaged. Consider bone metastases.  . . Knowing this result, sister Hu (pseudonym) fell to the bottom of her heart instantly, and the local hospital had no technology to treat it, so she could only go to other hospitals for treatment. Sister Hu’s (pseudonym) husband learned about this situation and immediately found a relative of her own. This relative happened to be a late stage of breast cancer, and now the treatment effect is also very good. Sister Hu (pseudonym) took this relative to consult the hospital where she was treated. After some understanding, sister Hu (pseudonym) decided to go to the hospital to see the situation first!  . . went directly to the hospital on September 23, “When I first came, I was still a little worried, but when I saw the treatment effect of other patients in the hospital, the feeling of doubts was dispelled.” Sister Hu (pseudonym) Say so. Sister Hu (pseudonym) received treatment at the hospital. In the hospital, Professor Yao Bo gave a treatment plan based on the condition of Sister Hu (pseudonym). After a period of treatment, sister Hu (pseudonym) lamented: “This technique is simply amazing. On the second day of surgery, the tumor pressure on the cervical spine disappeared. You can lie down and rest normally, and you can eat and drink. It went on normally. Surprise came too fast, and I didn’t respond. The whole treatment was very easy and innocent at all.” Sister Hu (pseudonym) after treatment CT scan . .Sister Hu (pseudonym) is in The fourth review said, “If it weren’t for this technique, I might not be able to support it today. Choosing the right doctor and choosing the right hospital is really very important. Only here can I have my second life.”
“Doctor, I heard that if I draw some blood, I can see if there is cancer in my body. I want to check it.” There are really a lot of people who come to consult and screen for tumors in this way. The “blood” they say is actually blood “tumor marker”. As far as lung cancer is concerned, there is no tumor marker that has a high diagnostic sensitivity and specificity for lung cancer, but it must be paid attention to when it is increased. Yes, these blood indicators are high, you may have a combination of multiple tumor markers for lung cancer detection, if significantly increased several times or even thousands of times, the possibility of cancer is extremely high. For lung cancer, if blood CEA (carcinoembryonic antigen), carbohydrate antigens CA125, CA153, cytokeratin fragments (CYFRA211, lung squamous cell carcinoma), squamous cell carcinoma antigen (SCC), tissue polypeptide antigen (TPA), At the same time, it is much higher, or several of these blood indicators are significantly increased. It is necessary to consider the possibility of non-small cell lung cancer (adenocarcinoma, squamous cell carcinoma, large cell carcinoma). Yes, these blood indicators are high, you may have lung cancer. If the blood test indicates: blood neuron specific enolase (NSE), gastrin releasing peptide precursor (Pro-GRP), creatine kinase BB ( CK-BB), chromogranin A (Cga) increased at the same time or multiple, mainly to consider small cell lung cancer. It should be noted that blood tumor markers may have different normal reference values in different hospitals. Do not directly compare them, so as not to scare yourself; also note that if the blood tumor markers increase slightly, don’t be nervous, choose a date Recheck once, if you still get higher, you have to consult an oncologist.
Genes are passed on from generation to generation, and cancer is a complex polygenic disease, so some tumors are indeed hereditary. The vast majority of tumors are caused by the interaction of environmental factors and genetic factors, of which genetic factors account for a considerable proportion. What are the common hereditary cancers? 01. Intestinal cancer has a disease called “familial adenomatous polyposis”, which can easily develop into intestinal cancer. It has been observed that if a parent has colon cancer due to “familial adenomatous polyps”, the genetic probability of their children is 50%. 02. Breast cancer In a family, if any one of the mother, daughter, and sister is diagnosed with breast cancer, the risk of cancer for other women will increase by a factor of two; if two women are diagnosed with breast cancer, the other women will suffer from cancer The risk is five times the average. 03. 5-10% of pancreatic cancer family members also have a history of the disease. If more than one first-degree relative (parents, children, siblings) suffers from the disease, the risk of the disease will increase significantly, and it usually occurs before the age of 50. Hereditary pancreatic cancer will increase the risk of onset before the age of 70 by about 30-40%. 04. Endometrial cancer According to statistics, about 5% of all patients with endometrial cancer suffer from cancer due to genetic factors. The characteristic is that these patients have an average age of onset than patients with sporadic endometrial cancer. The age is 10-20 years younger. 05. 5~10% of gastric cancers are hereditary gastric cancers. Among them, the most common ones are hereditary diffuse gastric cancers. Hereditary diffuse gastric cancer is an autosomal dominant genetic disease, and the probability of the offspring carrying the parental gene mutation is 50%. 06. Prostate cancer If a direct family member (brother or father) has prostate cancer, the risk of prostate cancer will double. Two or more immediate family members suffering from prostate cancer, the relative risk will increase by 5 to 11 times. 07. Melanoma Overall, about 8% of patients newly diagnosed with melanoma have a first-degree relative with melanoma. About 1 to 2% of patients diagnosed with melanoma have 2 or more close relatives with melanoma. . Are the inherited cancers the same? This is not necessarily. Some cancers have a certain heredity, but it is not necessarily the cancer itself that is inherited. As mentioned above, if the girl’s mother has breast cancer, will the girl definitely get breast cancer? no. But in addition to the possibility of breast cancer, girls also have a high risk of ovarian cancer, pancreatic cancer or melanoma. Why is this? At the genetic level, the root cause of cancer is a disease-causing mutation in a gene, and a gene-causing mutation can cause multiple cancers, which is not difficult to explain why different cancers occur in the same family. Therefore, there are many people in the family who have cancer, especially first-degree relatives (parents, children, siblings) who have cancer, you need to be vigilant, maybe a gene has a pathogenic mutation, which leads to hereditary tumors in the family .
Lung cancer is the malignant tumor with the highest incidence in the world, which seriously endangers human life and health. What are the common manifestations of lung cancer? Who should conduct lung cancer screening? What can be done to detect lung cancer early? 1. What are the clinical manifestations of lung cancer? 1. Typical manifestations: cough, often irritating dry cough, and some patients with alveolar cancer can see a large amount of mucus. In addition, hemoptysis, unexplained chest pain, and difficulty breathing are the most typical clinical manifestations of lung cancer. Most have difficulty breathing due to airway obstruction or pleural effusion. Respiratory symptoms over the age of 40 years can not be eliminated if the lung cancer is not relieved after 2 weeks of treatment; the following symptoms indicate that the cancer may have spread in the chest cavity: long-lasting unrelieved hoarse voice, edema of the head and neck or even both limbs, difficulty swallowing, heart rhythm Abnormality or pericardial effusion; Symptoms indicate extrathoracic diffusion: enlarged masses on the collarbone (lymph nodes), persistent bone pain (chest pain, back pain, etc.); b-ultrasound found solid space occupying; intracranial space occupying lesions ; 2. Atypical clinical manifestations: due to atypical, it is often easily overlooked. These include inexplicable progressive weight loss, unexplained anemia with panic dizziness and fatigue, unexplained fever, unilateral eyelid drooping pupil reduction, long-lasting clubbed toes, unexplained thigh muscle weakness, and male breast hyperplasia. 2. Who should conduct lung cancer screening? 1. The above-mentioned typical or atypical clinical manifestations of lung cancer; 2. Unclear, atypical lung abscess; 3. Tuberculosis patients, stable pulmonary tuberculosis lesion enlargement or anti-tuberculosis treatment is ineffective; 3. How to do otherwise Found early lung cancer? For people at high risk of lung cancer, it is recommended to conduct annual physical examinations for “lungs”. High-risk groups include: smoking history, long-term heavy smokers, especially more than 20 packs (400 cigarettes) per year for more than 15 years; patients with chronic pulmonary diseases, such as pulmonary fibrosis, tuberculosis, and chronic obstructive pulmonary disease; high-risk Professional practitioners who have been in an air polluted environment for a long time, or have been exposed to asbestos, asphalt, coal tar, diesel fuel, and gasoline for a long time; people with a family history of lung cancer; elderly people, 50 years or older should also have a physical examination every year;
It is understood that Hunan’s first “Radiation Superman”-Varian Vitalbeam settled in Xiangya Boai Hospital and put into clinical use. The Vitalbeam radiotherapy system is a brand-new product based on an intelligent accelerator platform, which can be used by clinical institutions to achieve modern precision and smart radiation treatment.  . Hunan’s first radiotherapy “superman” settled in Xiangya Boai and put it into clinical use, specializing in “difficult” tumors, and achieving precise “strike” To further relieve patients’ pain and allow patients to receive better treatment, Xiangya Boai Hospital was huge Introduced and activated Varian VitalBeam radiotherapy system. The introduction of this product, known as the pinnacle of cancer treatment, marks the Xiangya Boai radiotherapy technology, which has since entered the era of “precision orientation” and reached the international leader.  . Vitalbeam, a linear accelerator radiotherapy device with image guidance function produced by Varian, USA, combines image-guided radiotherapy technology (IGRT), intensity-modulated radiotherapy technology (IMRT), and three-dimensional conformal radiotherapy technology (3DCRT). Precise and intelligent radiotherapy for tumors is one of the most advanced special equipments for tumor radiotherapy in the world.  . Its difference from traditional radiotherapy technology can be roughly adapted to the “four most” 1. The maximum dose of radiation within a certain range of the tumor target area; 2. The minimum radiation dose of normal tissues around the tumor target area; 3. The tumor target area Dose distribution is the most uniform; 4. The most accurate and precise radiation therapy for tumor target area positioning and irradiation has the advantages of “high precision, high dose, high efficacy, and low damage” . Clinical application scope of the device This device is suitable for benign/malignant tumors in all parts of the body Indications for general radiotherapy and precision radiotherapy: The indications for tumor radiotherapy are very extensive. According to the sensitivity of tumor cells, the purpose of radiotherapy and the method of radiotherapy, the indications for radiotherapy are divided into 5 aspects:  .1 According to the radiosensitivity of the tumor . Radiation highly sensitive tumors: malignant lymphoma, testicular seminoma, nephroblastoma, neuroblastoma, medulloblastoma, Ewing sarcoma, small cell lung cancer, etc. Such tumors are highly malignant, develop rapidly, are prone to distant metastasis, and require combination chemotherapy to achieve better long-term efficacy.  . Radiation moderately sensitive tumors: head and neck squamous cell carcinoma, esophageal squamous cell carcinoma, lung squamous cell carcinoma, breast cancer, cervical cancer, skin cancer, etc. The development of such tumors is relatively slow, and the metastasis is relatively late, and simple radiotherapy can achieve good results.  . Low-radiation sensitive tumors: gastrointestinal adenocarcinoma, pancreatic cancer, prostate cancer, etc. High-dose irradiation is needed, appropriate radiation therapy is used to treat tumors while protecting normal tissues around the tumor, and good results can be achieved.  . Tumors with poor radiosensitivity: fibrosarcoma, liposarcoma, rhabdomyosarcoma and other tumors mostly derived from mesenchymal tissue. Radiotherapy is only used as an adjuvant treatment for surgery or palliative treatment after metastasis and recurrence.  . 2. Radiation therapy that preserves organ function . Not only achieves the same curative effect as radical surgery but also preserves organs and functions, such as breast-conserving surgery for early breast cancer, early laryngeal cancer, and low rectal cancer after anal preservation surgery.  .3. Comprehensive treatment of radiotherapy and surgery . The use of preoperative radiotherapy can reduce tumor staging and increase the rate of surgical resection. Postoperative radiotherapy can prevent and reduce the recurrence of local and regional lymph nodes, improve local control rate and prolong survival, such as breast cancer, rectal cancer, head and neck tumors and tumors with positive margins after surgery.  .4. Palliative radiotherapy . To achieve analgesia, reduce symptoms and improve quality of life without increasing the adverse effects of treatment, for example, distant tumors such as bone and brain metastases or local tumor recurrence.  .5. Benign lesions requiring radiotherapy . Hemangiomas, keloids, etc.  .
Colon cancer is a relatively common malignant tumor, especially the incidence rate has gradually increased in recent years, and surgical resection is the main treatment method for colon cancer. Patient friends often ask me: “Director, I have been a month after bowel cancer surgery. I don’t want to be treated with chemotherapy. Can you give me some Chinese medicine for treatment?”. This question is unclear in a word, because he needs to know his medical condition and treatment, how can the operation be done? Radical surgery or palliative surgery? What is the pathological stage after surgery? What is the degree of pathological differentiation? Are there any adverse prognostic factors for molecular biology? Generally speaking, if the surgery is palliative, it usually requires postoperative adjuvant chemotherapy. Studies have shown that chemotherapy can prolong the survival time, and it is difficult to control the disease simply with traditional Chinese medicine. During chemotherapy, Chinese medicine can be supplemented to increase efficacy and reduce toxicity. If radical surgery is performed, stage I patients can be simply surgically removed, and chemotherapy is generally not required, unless lymphatic vessels and vascular cancer thrombosis are formed. At this time, Chinese medicine can be taken appropriately from one month to half a year after surgery; After the best chemotherapy. Studies have shown that in stage II and III cases, postoperative adjuvant chemotherapy can increase the 5-year survival rate by about 10%. Similarly, Chinese medicine can be supplemented during chemotherapy to increase efficacy and reduce toxicity. In addition, there is an important job after colon cancer surgery is to regularly review. Generally, it should be rechecked once every 3 months to half a year after treatment, including CT examination of chest cavity and abdominal cavity, as well as the detection of serum CEA, CA199 and other tumor markers.
Cancer has always been a very frightening disease, so you must actively prevent cancer in your daily life. You can often eat some anti-cancer and anti-cancer foods, which can greatly reduce the chance of cancer. Common garlic, onions, soybeans, green tea, etc. are good choices, all have certain anti-cancer effects, 4 kinds of anti-cancer “star dishes”, eat right to prevent cancer, eat wrong and “carcinogenic”, see if you eat Is that right? Let’s get to know it together! —————Garlic and onion Garlic and onion are foods that many people love very much, and they contain a variety of anti-cancer ingredients, such as nitrosamines, aflatoxin, etc. Carcinogens all play a certain role in eliminating. Related studies have shown that eating foods such as garlic and onions daily can reduce the incidence of prostate cancer by 50%. Allicin in garlic can also inhibit the activity of tumor-generating enzymes and prevent Helicobacter pylori infection, but it must be eaten correctly and healthy. Carcinogenic eating method 1, grilled to eat & nbsp. & nbsp. & nbsp. Many people prefer to eat roasted garlic, roasted onions, these two spicy foods grilled to eat, the taste is more unique. But be aware that charcoal fuel contains benzopyrene, which is a carcinogen, which can adhere to food with smoke and then be eaten into the stomach. As a result, garlic and onions, which were originally anti-cancer, turned into cancer-causing food, so don’t eat them like this. 2. Soy pot . . .Garlic is often used as a kind of seasoning food. Using garlic soy pot is something that many people like to do. The flavor of the food is more intense and delicious. But be aware that once the oil temperature exceeds 180°C, the fatty acids in the vegetable oil will be oxidized, resulting in harmful substances such as aldehydes, ketones, and polycyclic aromatic hydrocarbon carcinogens. And the higher the temperature, the more oxidizing substances and carcinogenic substances are produced, so this method of eating is also undesirable. ————————————————– Soybean Soybean is a bean food that many people often eat. It contains a variety of isoflavones. Soy isoflavones are very similar to the human estrogen mechanism, so they are also called “phytoestrogens.” Appropriate consumption can effectively fight against the human body. The canceration process caused by estrogen deficiency, such as breast cancer or prostate cancer, but the wrong way to eat may also induce cancer. Carcinogenic Eating Method . . .If soybeans are stored improperly, causing the soybeans to get wet and then moldy, then it will cause a large amount of aflatoxin in the soybeans, which is a very strong carcinogen, if you eat it Such soybeans will greatly increase the risk of liver cancer, and the damage to health is huge. ————————————————– Green tea Green tea is a common drink, it is rich in nutrients, which contains a lot of free radicals beneficial to the human body, most famous for tea polyphenols. Tea polyphenols have very strong antioxidant properties, and can effectively eliminate human free radicals, enhance the immunity of human cells, and play a positive role in preventing and fighting cancer. Carcinogenic eating method . . . But research shows that if you drink hot tea for a long time (more than 65°C), it will greatly increase the risk of esophageal cancer, and the main cause of cancer is because the temperature of tea is too high. Therefore, when drinking green tea, the temperature of the tea must be well controlled, and it must not exceed 65°C. This is beneficial to health and can prevent cancer.
. In early 2010, Ms. Ye found that her cold and cough had been bad repeatedly. She went to the county hospital to check. The doctor said that it was pharyngitis. The treatment eased for a while, and it relapsed within a few days. After several months of repeated tossing and coughing, she went to the People’s Hospital of the city to have an enhanced CT. The result of the examination made Ms. Ye never expect that her lungs had a tumor that was 9 cm long.  . . Ms. Ye feels that she is in good health and usually has no serious illnesses. This time it was just a small cough and fever. Why did it suddenly become advanced lung cancer?  . Because the tumor is too large and the risk of the operation is too high, if you are not careful, it will be life-threatening. The doctor recommended that Ms. Ye give up the operation. But his child is still too young to die so early. Ms. Ye did not want to give up, and she consulted a famous domestic cancer specialist hospital for consultation. The result was the same. No surgery can be done, isn’t that waiting for death? Ms. Ye felt as if she had been sentenced to death and lost her hope of survival.  . . . On the occasion of despair, a patient in town told her that it would be better to go to Professor Yao Bo. He is an oncologist. The radioactive particle treatment is very effective. My liver cancer is cured by him Yes, this may be your only chance. The best oncology hospital experts say that there is no way, can he have a good way? But for the children at home and the husband who loves him, let’s try it.  . . Ye and his husband approached Professor Yao Bo with doubts. Professor Yao Bo analyzed the condition in detail based on Ms. Ye’s symptoms and medical records. Professor Yao said: According to the data, the diagnosis of advanced lung cancer is undoubtedly. The lung tumor is large and close to the large artery. As long as the scalpel touches the blood vessel slightly, it will immediately bleed and die. You have also been to a famous domestic cancer specialist hospital to understand that radiotherapy and chemotherapy have little meaning for this huge lung tumor, and in the end, there will be a lot of money. To treat such a high-risk disease, traditional treatments are outdated, and only new methods can create miracles!  . . The “precision three-dimensional overall tumor elimination method” that we have explored for more than 20 years is to integrate the most cutting-edge technology of modern cancer treatment on patients, and to achieve precise and targeted treatment of tumors. The metaphor of the image is that the tumor is like a honeycomb. In the past, radiotherapy was like an artillery era. The target was inaccurate and the lethality was insufficient. However, its own damage was very serious. The new treatment method first uses double arteriovenous intervention to block the growth of the horse’s honeycomb, and then uses radioactive particles to accurately attack the tumor from the inside, improving the ability to lock the target position of the tumor, and enhancing the ability to remove the tumor at a fixed point. “After a detailed explanation from Director Yao, Ms. Ye decided to choose treatment here. . . The operation was very successful. Ms. Ye’s body was not injured and she was discharged home soon. After several reviews, it was obvious Seeing that the tumors in the body are shrinking until they disappear. After being discharged from the hospital, Professor Yao Bo also made careful suggestions for Ms. Ye’s eating and rest habits. Over the past few years, Ms. Ye and his husband have come back every year to let Yao Bo Professor review.
