What causes nasopharyngeal cancer?

Nowadays, more and more people are suffering from nasopharyngeal cancer. Many people cannot understand how they got this disease. It is very important to understand the cause of the disease. Nasopharyngeal cancer is a common cancer disease in life. It harms many patients and infringes on their health. There are many factors that can cause nasopharyngeal cancer. This is knowledge that friends need to understand in depth. Let's take a look at the main causes 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 we need to pay attention to. Lymphoblastoid cell lines carrying Epstein-Barr virus were isolated from nasopharyngeal carcinoma tissues, and Epstein-Barr virus particles were found.

2. Living environment: With the acceleration of my country's industrialization, environmental pollution is becoming more and more serious. It is difficult to change the environmental pollution caused by industrialization in the short term. Although it is an irresistible factor, young people should be kind to themselves and their stomachs.

3. 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.

4. Lifestyle: Lifestyle is also an important cause of nasopharyngeal carcinoma. Many young people have irregular lifestyles, 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 insensitive to radiation is zero to ten percent, and the 5-year survival rate of radiosensitive lymphoepithelial carcinoma is about 30%.

After understanding the above knowledge, everyone has understood the specific cause of nasopharyngeal cancer. It can be seen that there are still many factors that cause nasopharyngeal cancer in daily life. I hope that friends can pay attention to the cause of the disease and carry out targeted prevention work for nasopharyngeal cancer.
