There are many cancers that people may get in their lifetime, such as lung cancer, bladder cancer, liver cancer, cervical cancer … And what we want to talk about is “nasopharyngeal cancer” that grows in our nasal cavity. Speaking of nasopharyngeal cancer, Li Zongwei, a retired Malaysian general, can’t help but think about 33 electric shocks during the fight against nasopharyngeal cancer. The entire throat is ruptured. An anesthetic is needed to eat something. It was also because of nasopharyngeal cancer that he left his favorite game. The incidence of nasopharyngeal cancer accounts for 60% of the entire otolaryngology malignant tumors. The age of onset of patients is usually between 30 and 50 years old, while the number of male patients is 2-3 times that of female patients. Although compared with other cancers, nasopharyngeal cancer is a more controllable cancer, but the harm to patients is also very great, which needs everyone’s attention. So, what are the causes of nasopharyngeal cancer? What are the symptoms to be careful of the arrival of nasopharyngeal cancer? In order to prevent and develop nasopharyngeal cancer early, we will talk about these two aspects specifically today. Nasopharyngeal cancer is a high incidence area in southern China. In fact, nasopharyngeal cancer is also known as “Guangdong cancer” because this kind of malignant tumor has a relatively high incidence in Guangdong, Guangxi, Fujian, Hunan, Jiangxi and Hubei. According to a Guangdong survey, the high incidence of nasopharyngeal cancer may be related to the low content of trace nickel in rice and water consumed locally. In addition, there are reports that eating salted fish and preserved food is the cause of the high incidence of nasopharyngeal cancer in southern China. In addition to the emergence of nasopharyngeal cancer caused by the environment and diet, family inheritance is also the reason why some people are susceptible to nasopharyngeal cancer. According to the survey, some southern Chinese descendants living in other countries still maintain a high incidence of nasopharyngeal cancer, and certain genetic genes that determine the human leukocyte antigen HLA are closely related to the occurrence of nasopharyngeal cancer. At the same time, EB virus infection is also one of the important causes of nasopharyngeal cancer. From the first time researchers detected EBV antibodies in the serum of patients with nasopharyngeal carcinoma in 1996, later studies showed that most of the most common nasopharyngeal carcinomas with squamous cell carcinoma are keratinized squamous cell carcinoma and EBV is present in almost all terminally differentiated squamous cell carcinomas, so this is also one of the causes of nasopharyngeal carcinoma. 5 kinds of symptoms, early detection and early treatment of cancer and face this malignant tumor, in order to minimize the pain of treatment, early detection and early treatment is critical, so if these symptoms of unknown etiology appear, we may have to think Quickly went to the hospital to check. 1. After nasopharyngeal cancer occurs in patients with nasopharyngeal cancer, bloody nasal mucus is a typical symptom in the early stage, that is, the snot out of the nasal cavity is found to be mixed with blood capillaries, and the nasal blood is habitually sucked back from the mouth. Generally, this kind of bleeding occurs after getting up in the morning. Sometimes because of the small amount of blood in the nose, it will often be negligent by the patient and mistaken for rhinitis or sinusitis. As a precaution, when there is a lot of blood in the nasal mucus, it is recommended to go to the hospital for examination. Is it because of nasopharyngeal cancer? 2. Migraine When a headache occurs, most people think that there is a problem with the head, and the headache may also be a problem with the cervical spine. At the same time, when the headache symptom is migraine, pain behind the cranial pillow or the neck, Need to be careful if it is nasopharyngeal cancer. Because many patients with nasopharyngeal cancer have symptoms of headache at the initial diagnosis, the reason is that tumors in the nasopharynx may damage the skull base and involve the cranial nerves. 3. There is a lump in the neck. Neck lymph node enlargement is also a relatively obvious symptom of nasopharyngeal cancer in the early stage. That is, patients will feel a lump on their necks, and this is an enlarged lymph node. Lymph node enlargement in patients with nasopharyngeal carcinoma is caused by tumor metastasis to cervical lymph nodes, which can occur unilaterally or bilaterally. Generally, when the neck mass is deemed to be ineffective for inflammation treatment, it is recommended that patients should seek medical attention in a timely manner to check whether it is a nasopharyngeal cancer problem. 4. Hearing loss and if there is tinnitus, hearing loss, and a sense of occlusion in the ear, you should also be careful whether it is the cause of nasopharyngeal cancer, because when the tumor of nasopharyngeal cancer presses on the eustachian tube, it will occur unilaterally. These symptoms such as sexual tinnitus or hearing loss are recommended to go to the otolaryngology department of the hospital for examination. 5. Looking at things with ghosting. In addition to causing damage to the patient’s ears, nasopharyngeal cancer, when you find yourself looking at things with ghosting, that is, “double vision”, this is not only a problem with the eyes themselves, it may also be a nasopharyngeal cancer zone Coming persecution. Because the tumor of nasopharyngeal cancer also violates the related nerves of the orbit or the eyeball, which can cause problems such as diplopia, protruding eyeballs, and decreased vision.
