What factors may be related to the cause of nasopharyngeal carcinoma?

Nasopharyngeal carcinoma is a common disease, and patients with nasopharyngeal carcinoma should receive treatment as soon as possible. What are the causes of nasopharyngeal carcinoma? Let the experts introduce it to you so that you can have a more comprehensive understanding of the causes of nasopharyngeal carcinoma , hoping to help you.

1. Environment and diet

Environmental factors are the cause of nasopharyngeal cancer. Through clinical research, experts have found that the content of trace element nickel in rice and water in areas with high incidence of nasopharyngeal cancer is higher than that in areas with low incidence. The nickel content is also high in the hair of nasopharyngeal cancer patients. Nickel may be a cancer-promoting factor. Dinitrosopyrazine is related to the occurrence of nasopharyngeal cancer. Eating salted fish and pickled foods is a high-risk factor for nasopharyngeal cancer in southern China, and is related to the age, duration, frequency and cooking method of eating salted fish. This is related to the high concentration of nitrosamine compounds in salted fish and pickled products;

2. Genetic factors

There is a racial and familial clustering of nasopharyngeal carcinoma patients, and nasopharyngeal carcinoma may be a hereditary disease. Recently, the correlation between certain genetic factors that determine HLA and nasopharyngeal carcinoma has been discovered. There are reports that chromosomal aberrations in peripheral blood lymphocytes in families with a high incidence of nasopharyngeal carcinoma are related to a certain genetic susceptibility to nasopharyngeal carcinoma, which is one of the causes of nasopharyngeal carcinoma.

3. Epstein-Barr virus infection

EB virus-infected cells can produce a variety of EB virus-specific antigens, including early antigens, shell antigens, membrane antigens, and nuclear antigens. After the human body is infected with EB virus, it will produce various corresponding antibodies. These antibodies can be used as serological diagnostic markers for nasopharyngeal carcinoma, but the positive rate of EA-IgA antibodies in normal people is higher, and it is not as specific as VCA-IgA in diagnosing nasopharyngeal carcinoma. Further studies have shown that the detection of EA-IgA antibodies in serum is more specific than VCA-IgA antibodies, but not as sensitive as VCA-IgA. People who are positive for VCA-IgA antibodies are at high risk of developing nasopharyngeal carcinoma, which is also the cause of nasopharyngeal carcinoma.
