Causes of nasopharyngeal cancer

Many factors in life can cause the occurrence of nasopharyngeal cancer. Many people will experience symptoms of this disease, which seriously harms the health of patients. Therefore, we must pay attention to nasopharyngeal cancer and correctly understand the inducing factors of nasopharyngeal cancer. What exactly are the factors that induce the occurrence of nasopharyngeal cancer?

Causes of nasopharyngeal cancer:

Nasopharyngeal carcinoma refers to a malignant tumor that occurs on the top and side walls of the nasopharyngeal cavity. It is one of the most common malignant tumors in my country, and its incidence rate ranks first among malignant tumors of the ear, nose and throat. Common clinical symptoms include nasal congestion, blood in mucus, stuffy ears, hearing loss, diplopia and headache. Most nasopharyngeal carcinomas are moderately sensitive to radiotherapy, and radiotherapy is the first choice for nasopharyngeal carcinoma. However, for highly differentiated cancers, advanced disease courses and recurrence after radiotherapy, surgical resection and chemotherapy are also indispensable means.

1. Epstein-Barr virus. Infection with this virus is a major cause of nasopharyngeal carcinoma, which is something that everyone needs to pay attention to. Lymphoblastoid cell lines carrying Epstein-Barr virus were isolated from nasopharyngeal carcinoma tissues, and Epstein-Barr virus particles were found. Living environment. With the acceleration of my country's industrialization process, environmental pollution is becoming more and more serious. The environmental pollution caused by industrialization is difficult to change in the short term. Although it is an irresistible factor, young people should treat themselves and their stomachs well.

2. Psychological pressure. Young people are in the development period of their careers, so they are prone to anxiety, tension and other negative emotions in their daily work. Nowadays, young people are under great pressure in life, and they are always in a state of emergency mentally, which will induce intestinal diseases in a feedback manner. Lifestyle is also an important cause of nasopharyngeal carcinoma. Many young people have irregular lives, and drinking and smoking will affect their health. Many young people have no fixed place to live, no fixed jobs, like to stay up late to surf the Internet, and love to drink carbonated beverages, so they are infected with nasopharyngeal carcinoma at a young age. Nasopharyngeal carcinoma is mainly treated with radiotherapy, and residual lesions can be surgically removed. The irradiation range includes the nasopharynx, skull base, neck and orbit. The primary lesion dose is 65-70Gy, and the secondary lesion is 50-60Gy. Because the tumor is prone to recurrence and early metastasis, the prognosis is poor. The 5-year survival rate of squamous cell carcinoma that is not sensitive to radiation is zero to ten percent, and the 5-year survival rate of radiosensitive lymphoepithelial carcinoma is about 30%.

Prevention of nasopharyngeal cancer:

If you want to treat nasopharyngeal cancer, you have to go through surgery. In addition to spending a lot of money, it may also leave ugly scars. Therefore, we must do a good job of prevention before nasopharyngeal cancer occurs. Nasopharyngeal cancer is very harmful. Once you have nasopharyngeal cancer, the health of nasopharyngeal cancer patients will be seriously affected. Nasopharyngeal cancer affects the patient's life and work, and causes great psychological obstacles to the patient. Therefore, we must do a good job of preventing nasopharyngeal cancer and preventing the occurrence of nasopharyngeal cancer to avoid nasopharyngeal cancer causing harm to patients.

Prevent colds. Actively treat acute rhinitis, diseases of organs adjacent to the nose, and systemic diseases to prevent the induction of this disease. Avoid staying in an environment with toxic or irritating gases and dust for a long time. In addition, patients should not blow their noses vigorously to prevent turbid mucus from entering the ears. Do not use vasoconstrictive nasal drops, such as ephedrine and nose-eye cleansing, for a long time to avoid drug-dependent rhinitis. Pay attention to the dietary structure, do not be partial to food, and eat more vegetables, fruits and other foods containing a lot of vitamins. Eat less or no salted fish, pickled meat, etc. Eat less or no foods containing nitrosamines. Secondly, it is best for people over 40 years old to do a nasopharyngeal examination at the same time when they have a health check. Participate in sports in moderation to enhance your ability to resist diseases. Quit smoking and drinking. Avoid exposure to heavily polluted external air environments as much as possible. Because the nasopharynx is the only way for external air to enter the lungs, harmful gases first invade the nasopharynx before entering the lungs. These are the daily prevention points for nasopharyngeal cancer.

This is the knowledge about the causes of nasopharyngeal cancer. I hope friends can be alert to the occurrence of nasopharyngeal cancer, be careful about their own health, and pay attention to the prevention of nasopharyngeal cancer in life. It is necessary to attach importance to the knowledge of this disease. If the prevention is targeted at the cause, it can be more accurate and stay away from harm.
