summary

In fact, it's not very clear why nasopharyngeal carcinoma occurs now. It's not believable. The main reason is that it has a great relationship with heredity. There are also some viral infections, and then there are some environmental reasons. In fact, patients with nasopharyngeal carcinoma generally have racial or family aggregation, such as those living abroad in South China In the general condition, the incidence rate of NPC is relatively high. The study also found that certain genetic factors that determine human leukocyte antigen are closely related to the occurrence and development of NPC.

What causes nasopharyngeal carcinoma

First, there is the content of trace element nickel in rice and water in the high incidence area of nasopharyngeal carcinoma, which is generally higher than that in the low incidence area, and the content of nickel in the hair of patients with nasopharyngeal carcinoma is generally higher. Then animal experiments confirmed that nickel can promote nitrosamine induced nasopharyngeal carcinoma, vitamin deficiency and sex hormone imbalance can also change the sensitivity of mucosa to carcinogens.

Second: in fact, nasopharyngeal carcinoma refers to malignant tumors that occur in the nasopharyngeal mucosa. Generally speaking, it mainly occurs in Guangdong, Guangxi, Fujian, Hunan and other places in China. Generally, there are more males than females, and most of them are middle-aged people.

Third: teenagers also have it. However, it is relatively rare in general. There is a greater relationship between etiology and race. In general, the probability of nasopharyngeal carcinoma in yellow people is higher than that in white people, and it is also related to genetic factors and EB virus infection.

matters needing attention

In fact, it is not very clear why nasopharyngeal carcinoma occurs now. Generally speaking, it is mainly believed that there is a great relationship between nasopharyngeal carcinoma and family heredity, and there are also some bacterial infections. Of course, there is also a great relationship between nasopharyngeal carcinoma and environment.
