What causes nasopharyngeal cancer

Many people will have nasopharyngeal cancer in life. People don’t know much about this disease. However, once this disease occurs, it is extremely harmful and seriously affects the physical and mental health. It is very harmful to the patient’s body. Therefore, everyone needs to pay attention to the occurrence of this disease. So, what are the common causes of nasal cancer?

1. EBV virus infection.

Clinically, through long-term investigations, we know that EBV infection is closely related to the occurrence of nasopharyngeal carcinoma. Most keratinizing squamous cell carcinomas and most undifferentiated squamous cell carcinomas contain EBV. The body's immune function controls EBV infection through cellular immune function, and the probability of nasopharyngeal carcinoma is very high.

2. Chemical factors.

Through investigation, we know that when hair is rich in nickel, the possibility of nasopharyngeal cancer is relatively high. Nickel has a promoting effect on nitrosamines, and formaldehyde is also a very important factor in inducing nasopharyngeal cancer. The occurrence of the disease is not only related to nitrosamines, polycyclic aromatic hydroxyls, and trace elements of nickel, but also closely related to the cooking methods and shelf life in daily diet.

3. Genetic factors.

The occurrence of nasopharyngeal cancer has a clear family history, and the phenomenon of family clustering is also very serious. If there is a patient with nasopharyngeal cancer among family members, the probability of their offspring developing the disease is much higher than that of other people. The offspring of southern Chinese living in other countries also have a very high chance of developing nasopharyngeal cancer, which is hereditary.
