How is nasopharyngeal carcinoma inherited

In fact, a large proportion of nasopharyngeal cancer patients are caused by genetic factors. Below, let the experts introduce the causes of nasopharyngeal cancer to everyone, hoping to help everyone learn more about the causes of nasopharyngeal cancer and how nasopharyngeal cancer is inherited. The relevant content is as follows:

1. Genetic factors: If one of the first-degree relatives suffers from nasopharyngeal cancer, the probability of suffering from nasopharyngeal cancer is about 19.2 times higher than that of other people. In addition to genetic factors, the biggest reason may be that they live in the same environment. This is also one of the causes of nasopharyngeal cancer.

2. Environmental reasons: Chemical substances in the environment can cause nasopharyngeal cancer. These environmental reasons include childhood diet, living environment, work environment, and bad habits such as smoking, drinking, and chewing betel nuts, which may all be factors that cause nasopharyngeal cancer.

3. Viral infection: Nasopharyngeal carcinoma is the second cancer that has been suggested to be related to the Epstein-Barr virus. There is a type of Epstein-Barr virus antibody that is very high in nasopharyngeal carcinoma patients. After recovery, the antibody decreases; when the disease relapses or metastasizes, the antibody increases again. These phenomena confirm that the Epstein-Barr virus is related to the cause of nasopharyngeal carcinoma.

Genetic factors are one of the most common causes of nasopharyngeal carcinoma. There is a racial and familial clustering of nasopharyngeal carcinoma patients. 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 genetic susceptibility to nasopharyngeal carcinoma.

EB virus infection can also easily lead to the occurrence of nasopharyngeal carcinoma. Cells infected with EB virus 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 relatively high, and it is not as specific as VCA-IgA in diagnosing nasopharyngeal carcinoma. Therefore, this is also the main cause of nasopharyngeal carcinoma.

The above is an introduction to the genetic factors of nasopharyngeal carcinoma. If someone in your family history has nasopharyngeal carcinoma, then you should pay attention. Take precautions in advance and seek medical treatment in time if problems arise. Believe that the disease will stay away from you.
