What causes nasopharyngeal cancer?

Common symptoms of nasopharyngeal carcinoma include nasal congestion, blood in mucus, stuffy ears, hearing loss, double vision and headaches. Understanding the factors that cause nasopharyngeal carcinoma is beneficial for treatment and prevention. Environmental factors may play an important role in the development of nasopharyngeal carcinoma. Let's learn what causes nasopharyngeal carcinoma.

Environmental factors: The report shows that the mortality rate of nasopharyngeal cancer among Chinese who have emigrated abroad gradually decreases with the number of generations. On the contrary, the risk of nasopharyngeal cancer among Caucasians born in Southeast Asia has increased. This shows that environmental factors may play an important role in the development of nasopharyngeal cancer.

Chemical factors: In some areas with a high incidence of nasopharyngeal cancer, such as Guangdong and Guangxi, residents often eat salted fish, pickled meat, pickled vegetables and other foods. These foods contain a large amount of nitrite, a certain amount of nitrosamines and various compounds, which can easily lead to the occurrence of nasopharyngeal cancer.

Genetic factors: The incidence of nasopharyngeal carcinoma has obvious regional, racial and familial clustering. Nasopharyngeal carcinoma is more common in the yellow race, and rarely in the white race. The descendants of ethnic groups with high incidence rates tend to maintain high incidence rates even if they move to other places. Patients with nasopharyngeal carcinoma often have a clear family history.

Precautions: Pay attention to climate change, prevent colds, keep your nose and throat clean, gargle several times a day, and rinse your nasopharynx when necessary to avoid viral infection. Try to avoid inhaling harmful fumes, such as kerosene lamp gas, insecticide aerosols, etc., and actively quit smoking and drinking. If you have nasopharyngeal diseases, you should seek medical treatment as soon as possible. If you find blood in your nasal discharge or after sniffing your nose,
