Several major causes of nasopharyngeal carcinoma

Nasopharyngeal cancer is a disease that many people know about in life, but many nasopharyngeal cancer patients do not know why they get it. Below, I will tell you in detail what the specific factors of nasopharyngeal cancer are.

1. Genetic susceptibility: This is one of the common causes of nasopharyngeal carcinoma. 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. Epstein-Barr virus (EBV) infection: Studies have shown that EBV infection is closely related to the occurrence of nasopharyngeal carcinoma. EBV is present in most keratinizing squamous cell carcinomas and almost all undifferentiated squamous cell carcinomas. Most people in the world have been infected with EBV in childhood, but only a small number of people develop nasopharyngeal carcinoma in adulthood. Therefore, this is a factor that causes nasopharyngeal carcinoma.

3. Environmental factors: This is also a cause of nasopharyngeal cancer. The content of trace element nickel in rice and water in high-risk areas of nasopharyngeal cancer is higher than that in low-risk areas. The content of nickel in the hair of nasopharyngeal cancer patients is also higher than that in low-risk areas. Animal experiments show that nickel can promote nitrosamines to induce nasopharyngeal cancer. People who are easily exposed to formaldehyde in life are also prone to nasopharyngeal cancer. There are also reports that eating salted fish and pickled food is a high-risk factor for nasopharyngeal cancer, and it is also related to the age of eating salted fish, the period of consumption and the cooking method.

The above is a detailed description of the causes of nasopharyngeal cancer. I hope it can help everyone understand the knowledge of nasopharyngeal cancer and cure it in time. If you have other questions about nasopharyngeal cancer, you can contact our online experts to answer your questions.
