What factors may lead to nasopharyngeal tumors

Nasopharyngeal tumor is one of the most common tumors in my country, and ranks first in the incidence of head and neck malignant tumors. In particular, the incidence rate in Guangdong ranks first in the country. The main pathogenic factors of nasopharyngeal tumor are as follows.

1. Epstein-Barr virus infection

2. Environment and diet: Environment is also one of the pathogenic factors of nasopharyngeal tumors. Investigations have found that the content of trace element nickel in rice and water in areas with high incidence of nasopharyngeal tumors is higher than that in areas with low incidence, and the nickel content in the hair of nasopharyngeal tumor patients is also high. Animal experiments have shown that nickel can promote nitrosamine-induced nasopharyngeal tumors. It has also been reported that eating salted fish and pickled food is a high-risk factor for nasopharyngeal tumors in southern China, and is related to the age of eating salted fish, the period of consumption, and the cooking method.

3. Genetic factors: There is a racial and familial clustering of nasopharyngeal tumor patients. For example, the descendants of southern Chinese living in other countries still have a high incidence of nasopharyngeal tumors, which suggests that nasopharyngeal tumors may be a hereditary disease.

The age of onset of nasopharyngeal tumors is mostly between 40 and 60 years old, with more men than women. People in the high-risk group should pay more attention to avoiding the pathogenic factors of nasopharyngeal tumors as much as possible.
