What are the main causes of nasopharyngeal carcinoma

summary

There are many causes of nasopharyngeal carcinoma, so many people in our life have been hurt by this disease. This disease has the characteristics of family inheritance. Therefore, in our daily life, we suggest that this kind of people pay more attention to understand the high risk factors of nasopharyngeal carcinoma, so that we can achieve targeted prevention of nasopharyngeal carcinoma to reduce the possibility of recurrence in time. Here is a detailed introduction to the etiology of nasopharyngeal carcinoma, hoping to help you.

What are the main causes of nasopharyngeal carcinoma

First, EB virus infection. Studies have shown that EBV infection is closely related to the occurrence of nasopharyngeal carcinoma. EBV exists in most keratinized squamous cell carcinoma and almost all undifferentiated squamous cell carcinoma. Most people in the world have been infected with EBV in childhood, but only a few of them have nasopharyngeal carcinoma in adulthood. The pathogenic mechanism of EBV is still unclear. The control effect of immune system on EBV infection and the mechanism of EBV escaping immune response are the focus of research.

Second, environment and diet. Environmental factors are also a cause of nasopharyngeal carcinoma. In Guangdong Province, the content of trace element nickel in rice and water in high incidence area of nasopharyngeal carcinoma is higher than that in low incidence area. The content of nickel in hair of patients with nasopharyngeal carcinoma is also higher than that in low incidence area. The animal experiment showed that nickel could promote the induction of nasopharyngeal carcinoma by nitrosamine. It has also been reported that eating salted fish and salted food is a high risk factor for nasopharyngeal carcinoma in southern China, and it is also related to the age of eating salted fish, the amount of time and cooking methods.

Third, genetic factors. Nasopharyngeal carcinoma patients have racial and familial aggregation phenomena, China's southern population living in other countries still has a higher incidence rate of NPC.

matters needing attention

The incidence of nasopharyngeal carcinoma is mainly more than that of men. Clinical data show that male patients are significantly higher than female patients, which is about two times of the gap. Therefore, we suggest that the high incidence group of nasopharyngeal carcinoma in daily life should pay more attention to physical examination.
