Gas factors that cause nasopharyngeal cancer

Common symptoms of nasopharyngeal carcinoma include nasal congestion, blood in mucus, stuffy ears, hearing loss, double vision and headache. Understanding the gas factors that cause nasopharyngeal carcinoma is beneficial to treatment and prevention. Let's learn about it together.

Viral factors: More than 90% of people in my country have been infected with Epstein-Barr virus when they were young. The so-called Epstein-Barr virus is a human herpes virus. Immunological and biochemical studies have confirmed that the Epstein-Barr virus is closely related to nasopharyngeal carcinoma, but the details are still unclear.

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.

People should pay attention to climate changes, prevent colds, maintain nasal and throat hygiene, gargle several times a day, and flush the nasopharynx when necessary to avoid viral infections.
