Experts explain the common causes of nasopharyngeal cancer

The medical cause of nasopharyngeal cancer is quite complicated. Many oncologists have different opinions. Some of the causes of nasopharyngeal cancer are generally recognized. So what are the common causes of nasopharyngeal cancer? Let's talk about the common causes of nasopharyngeal cancer.

In general, the common causes of nasopharyngeal carcinoma are:

1. Virus factors are a common cause of nasopharyngeal carcinoma. In 1964, Epstein and Barr cultivated a herpes-like virus called EB virus in their research on nasopharyngeal carcinoma tissue. Since then, some scholars have detected EB virus antibodies in the blood of nasopharyngeal carcinoma patients, with a detection rate of 90%. EB virus has also been isolated from lymphoblasts cultured from nasopharyngeal carcinoma living tissue. Chinese scholars have also confirmed that nasopharyngeal carcinoma patients have higher specific antibodies. At the same time, it was found that people in high-incidence areas of nasopharyngeal carcinoma have higher antibody levels than people in low-incidence areas. Some researchers have inoculated animals with EB virus, which can induce fatal malignant reticulocytosis in animals. When animal lymphocytes are cultured in vitro, they can be malignantly transformed by EB virus. The above research further confirms the important role of EB virus in the etiology of nasopharyngeal carcinoma.

2. Genetic factors are also a common cause of nasopharyngeal carcinoma. Nasopharyngeal carcinoma has a genetic tendency. According to clinical data, the cause of nasopharyngeal carcinoma has a clear racial tendency, mainly seen in the yellow race, while the incidence rate of blacks and whites is extremely low. Family clustering was found in patients in high-incidence areas. About 10% of patients have a family history of cancer, and there are several people in the same family who are sick.

3. Environmental factors. Studies have shown that there are many chemical substances in the environment, such as polycyclic hydrocarbons, nitrosamines and fungal toxins, which are related to the cause of nasopharyngeal cancer. Epidemiological survey data show that residents in areas with a high incidence of nasopharyngeal cancer are accustomed to eating salted fish since childhood. Experiments have shown that the salted fish they eat contains nitrosamine compounds. Feeding rats with this salted fish can induce nasal and paranasal sinus cancer. Therefore, this regional eating habit may also be a common cause of nasopharyngeal cancer.

The above is an introduction to the common 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.
