Causes of nasopharyngeal carcinoma

summary

The common symptoms of nasopharyngeal carcinoma are nasal congestion, blood in the nose, ear congestion, hearing loss, diplopia and headache. I suffered from nasopharyngeal carcinoma last year. After a period of treatment in the hospital, my condition has been controlled to a certain extent. In the process of treatment, I have a certain understanding of the causes of nasopharyngeal carcinoma. I would like to share with you the causes of nasopharyngeal carcinoma. I hope you can take precautions.

Causes of nasopharyngeal carcinoma

One of the influencing factors: the virus factor: more than 90% of people in our country have been infected with EB virus when they were young. The so-called EB virus is human herpesvirus. The relationship between Epstein Barr virus (EBV) and nasopharyngeal carcinoma (NPC) has been confirmed by immunological and biochemical studies.

The second influencing factor: environmental factor: the report shows that the mortality rate of nasopharyngeal carcinoma in Chinese emigrants gradually decreases with the genetic generation. On the contrary, Caucasians born in Southeast Asia have a higher risk of nasopharyngeal carcinoma. This suggests that environmental factors may play an important role in the pathogenesis of NPC.

The third influencing factor: genetic factor: the incidence of nasopharyngeal carcinoma has obvious regional, ethnic and familial aggregation. Nasopharyngeal carcinoma is more common in yellow people than in white people. The high incidence rate of ethnic groups, even if they migrate to their descendants, still maintain a high incidence rate. Nasopharyngeal carcinoma patients often have obvious family history.

matters needing attention

Pay attention to climate change, prevent cold, keep nose and throat clean, gargle several times a day, and wash nasopharynx cavity when necessary to avoid virus infection. Try to avoid harmful smoke, such as kerosene lamp gas, insecticide aerosol, and actively quit smoking and alcohol. Early diagnosis and treatment of nasopharynx diseases should be carried out. In case of bloody nasal discharge or bloody nasal discharge after nasal suction, as well as unexplained cervical lymphadenopathy and middle ear effusion, detailed examination of nasopharynx should be carried out in time, which is very important for the prevention of nasopharyngeal carcinoma.
