What is the cause of gastric cancer

summary

My grandfather always has a bad stomach. Some time ago, he was diagnosed with gastric cancer, which belongs to the early stage of gastric cancer. He had surgery in time, but the recovery was not very good. Today, I'll introduce the causes of gastric cancer.

What is the cause of gastric cancer

First, the causes of gastric cancer are environmental factors. According to the results of the national comprehensive investigation of gastric cancer, the high incidence areas of gastric cancer are often concentrated in volcanic rocks, and the content of nickel and cobalt in drinking water is high, while the content of selenium is low; the low incidence areas of gastric cancer are often concentrated in limestone, and the content of trace elements in drinking water is opposite to the former. Studies have shown that elements such as nickel and cobalt can cause cancer or promote cancer, while selenium can inhibit cancer.

Secondly, the causes of gastric cancer are poor diet structure and dietary behavior. (1) the residents in the high incidence area of gastric cancer like to eat smoked dried meat, salted fish or crab sauce. The lack of fresh vegetables, fruits and milk in the diet has been confirmed by many studies, which is a significant feature of patients with gastric cancer or people in high incidence areas of gastric cancer. People in high incidence areas of gastric cancer in China often eat moldy food stored for a long time, and Aspergillus versicolor, Aspergillus flavus, Aspergillus nidulans and other molds can be detected in their gastric juice. Aspergillus versicolor toxin and aflatoxin produced by these molds can induce gastric cancer.

Finally, the causes of gastric cancer are genetic factors, gastric cancer has familial aggregation. Although the same living conditions and eating habits can make the family members living together susceptible to a certain disease, but this susceptibility is usually manifested in the parents and children who have direct blood relationship, rarely between the husband and wife living together. This shows that in addition to dietary habits, living conditions and other factors in the role of cancer, there must be genetic factors.
