Brief analysis of the causes of nasopharyngeal carcinoma

According to the latest survey and research, the incidence of nasopharyngeal cancer in China is higher than in other countries in the world. So what are the causes of nasopharyngeal cancer ? Let's ask an expert to introduce to you the causes of nasopharyngeal cancer.

The cause of nasopharyngeal carcinoma is currently unknown. It is speculated that genetic factors and traditional lifestyle habits may play an important role in the occurrence of nasopharyngeal carcinoma.

Genetic factors: Based on the research on cell chromosomes and human histocompatibility antigens (HLA), the obvious ethnic clustering of nasopharyngeal carcinoma leads to the speculation that the cause of nasopharyngeal carcinoma may be related to a polygenic genetic factor.

Environmental factors: Environmental factors are also one of the causes of nasopharyngeal cancer. Eating too much salted fish, cured meats, and pickled foods containing nitrosamine compounds can induce nasopharyngeal cancer. Drinking water has high levels of nickel and lead, while zinc, copper, and cadmium are relatively low. Rice has a high nickel content, while molybdenum, chromium, lead, and cadmium are low. Changes in these trace elements may also be related to the occurrence 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.

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 patients with severe disease. As the disease recovers, the antibody titer decreases, indicating that Epstein-Barr virus is closely related to the cause of nasopharyngeal carcinoma.

The above is an introduction to the causes of nasopharyngeal carcinoma. I hope it will be helpful to everyone. Understanding and recognizing the causes of nasopharyngeal carcinoma can help nasopharyngeal carcinoma patients receive better treatment and control the deterioration of the disease.
