What are the factors that induce nasopharyngeal cancer?

What is the cause of nasopharyngeal cancer? Nasopharyngeal cancer is a common type of cancer, and the cause of nasopharyngeal cancer is also very complicated, so many patients do not know much about the cause of nasopharyngeal cancer . Let's take a look at how experts answer the question of the cause of nasopharyngeal cancer.

Causes of nasopharyngeal cancer:

1. Epstein-Barr virus : At present, it cannot be considered that Epstein-Barr virus is the cause of nasopharyngeal carcinoma. In the development of nasopharyngeal carcinoma, Epstein-Barr virus is likely to exert its carcinogenic effect only with genetic factors and/or certain specific environmental factors as the prerequisite.

2. Environmental factors : Environmental factors play an important role in the occurrence of nasopharyngeal carcinoma. Substances associated with the occurrence of nasopharyngeal carcinoma include: (1) Nitrosamines: They can induce animal tumors, including dimethylnitrosamine and dihexylnitrosamine. (2) Aromatic hydrocarbons: In homes in areas with a high incidence of nasopharyngeal carcinoma, the content of 3,4-benzopyrene per gram of smoke is as high as 16.83µg, which is significantly higher than that in homes in areas with a low incidence.

3. Genetic susceptibility : According to Mendel's genetic positioning, nasopharyngeal carcinoma is not a hereditary disease, but the findings from epidemiological studies suggest that genetic background plays a very important role in the development of nasopharyngeal carcinoma. The main research focuses on human leukocyte antigen, sister chromatid crossing rate, chromosome fragile sites and aberrations.

The above are the causes of nasopharyngeal carcinoma. Through the introduction of experts, I believe you have a certain understanding of the causes of nasopharyngeal carcinoma. If you have any questions about the causes of nasopharyngeal carcinoma, please consult our online experts.
