What are the causes of nasopharyngeal cancer?

Nasopharyngeal carcinoma is a malignant tumor and one of the more familiar diseases. However, few patients know the causes of nasopharyngeal carcinoma. So what are the causes of nasopharyngeal carcinoma ? Let's take a look.

The main causes of nasopharyngeal cancer are:

1. 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.

2. Environmental factors : Environmental factors play an important role in the occurrence of nasopharyngeal carcinoma. Substances related to the occurrence of nasopharyngeal carcinoma include: (1) Nitrosamines: They can induce animal tumors. Among them, dimethylnitrosamine and dihexylnitrosamine are found in high levels in Guangzhou salted fish. It is believed that the high incidence of nasopharyngeal carcinoma in Guangdong people may be related to the habit of eating salted fish in childhood. (2) Aromatic hydrocarbons: In families in areas with a high incidence of nasopharyngeal carcinoma, the content of 3,4-benzopyrene in each gram of smoke is as high as 16.83µg, which is significantly higher than that in families in areas with a low incidence.

3. 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 play a carcinogenic role only with genetic factors and/or certain specific environmental factors as the prerequisite.

The above are the causes of nasopharyngeal cancer. I believe you have a certain understanding of the causes of nasopharyngeal cancer. In fact, there are many factors in life that cause nasopharyngeal cancer, so you must pay attention to preventing nasopharyngeal cancer in your daily life.
