Analysis of factors related to the cause of nasopharyngeal carcinoma

There are many factors related to the cause of nasopharyngeal carcinoma in medicine. Understanding the cause of nasopharyngeal carcinoma is crucial to the treatment of nasopharyngeal carcinoma. What are the common factors related to the cause of nasopharyngeal carcinoma ? Let's talk about the factors related to the cause of nasopharyngeal carcinoma.

In general, the common factors related to the cause of nasopharyngeal carcinoma are:

1. Epstein-Barr virus infection

Studies have shown that EBV infection is closely related to the etiology 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. The pathogenic mechanism of EBV is not yet fully understood. The control of the body's immune system over EBV infection and the mechanism by which EBV evades the body's immune response are the focus of research. The body's immune system controls EBV infection mainly through cellular immunity. Studies in recent years have shown that EBV can not only infect B lymphocytes, but also T and/or NK cells, and produce a large amount of cytokine I.

2. Environment and diet

Environmental factors are also important causes of nasopharyngeal cancer. According to the survey, 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, and 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, which are common causes of 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 the cause of nasopharyngeal cancer in southern China, and it is also related to the age of eating salted fish, the period of consumption and the cooking method.

The above is an introduction to the common factors related to the causes of nasopharyngeal cancer. I hope it will be helpful to everyone. Once you have nasopharyngeal cancer, you must go to the hospital for treatment in time to avoid serious delays in the disease.
