What is the cause of nasopharyngeal carcinoma

summary

I'm not in good health now. My nose is not very comfortable all the time. I often have a runny nose. In recent days, my condition is quite serious. I have nosebleed several times. My examination says it's nasopharyngeal carcinoma. I've done radiotherapy and chemotherapy, but the effect is not very good. In order to prevent this situation, let me introduce to you the reasons for nasopharyngeal carcinoma.

What is the cause of nasopharyngeal carcinoma

Reason 1: according to the study of cell chromosome and human histocompatibility antigen (HLA), the obvious ethnic aggregation of nasopharyngeal carcinoma (NPC) suggests that NPC may be a disease related to polygenic genetic factors.

Reason 2: environmental factors are also a cause of nasopharyngeal carcinoma. Eating too much salted fish, cured meat and salted food containing nitrosamines can induce nasopharyngeal carcinoma. The contents of nickel and lead in drinking water are high, but the contents of zinc, copper and cadmium are relatively low.

The third reason: the EB virus like lymphoblastoid cell line was isolated from nasopharyngeal carcinoma tissue, and the EB virus particles were found. There are high titers of EBV antibody in nasopharyngeal carcinoma. The titer of EBV antibody is high in patients with severe disease. With the recovery of the disease, the titer of EBV antibody decreases.

matters needing attention

Special reminder: reasonable diet can reduce the risk of cancer. In the daily diet to eat more grains, choose lean meat, eat more fruits and vegetables. Choose more foods containing antioxidants to increase fiber intake.
