What is the cause of nasopharyngeal cancer? What is the good diet for patients with nasopharyngeal cancer?

The cause of the disease is related to racial susceptibility, with Asians being more susceptible than Caucasians, genetic factors, and Epstein-Barr virus infection. Nasopharyngeal carcinoma is highly malignant and can metastasize to cervical lymph nodes in the early stages.

The causes of nasopharyngeal carcinoma may be related to the following factors:

①EB virus infection.

② Environment and diet: Environmental factors are also a cause of nasopharyngeal cancer. In Guangdong, a survey found that the content of trace element nickel in rice and water in areas with a high incidence of nasopharyngeal cancer was higher than that in areas with a low incidence. The nickel content in the hair of nasopharyngeal cancer patients is also high. Animal experiments have shown that nickel can promote nitrosamine-induced nasopharyngeal cancer. It has also been reported that eating salted fish and pickled food is a high-risk factor for nasopharyngeal cancer in southern China, and it is related to the age of eating salted fish, the period of consumption, the amount and cooking method.

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