Experts answer questions about the main causes of nasopharyngeal cancer

With the increasing incidence of cancer, more and more people are beginning to pay attention to various cancers, nasopharyngeal cancer is one of them, especially the causes of nasopharyngeal cancer. What are the common causes of nasopharyngeal cancer ? Let's talk about the common causes of nasopharyngeal cancer.

In general, the common causes of nasopharyngeal cancer are:

1. Environmental factors: Environmental factors are common causes of nasopharyngeal cancer. Eating too much salted fish, cured meats, and pickled foods containing nitrosamine compounds can induce nasopharyngeal cancer. Drinking water contains high levels of nickel and lead, while zinc, copper, and cadmium are relatively low. Rice contains high levels of nickel, while molybdenum, chromium, lead, and cadmium are low. Changes in these trace elements may also be related to the cause of nasopharyngeal cancer. In Guangdong, surveys found that the content of trace element nickel in rice and water in areas with a high incidence of nasopharyngeal cancer is higher than in areas with a low incidence. The nickel content is also high in the hair of nasopharyngeal cancer patients. Animal experiments have shown that nickel can promote nitrosamine-induced nasopharyngeal cancer.

2. Genetic factors: Based on the research on cell chromosomes and human histocompatibility antigens (HLA), the obvious ethnic clustering of nasopharyngeal carcinoma leads to the assumption that nasopharyngeal carcinoma may be a disease related to polygenic genetic factors. This is also a common cause of nasopharyngeal carcinoma.

3. Epstein-Barr virus: Lymphoblastoid cell lines carrying Epstein-Barr virus were isolated from nasopharyngeal carcinoma tissues, and Epstein-Barr virus particles were found. High titer antibodies to Epstein-Barr virus exist in nasopharyngeal carcinoma, and the titer is high in severe cases. As the disease recovers, the antibody titer decreases, indicating that Epstein-Barr virus is closely related to the etiology of nasopharyngeal carcinoma.
