Three causes of gastric cancer

The causes of gastric cancer are very complex, and many factors may induce the deterioration of gastric cells. However, experts have found that many causes are related to the formation of gastric cancer. Today, experts will tell us in detail about the causes of gastric cancer .

The main causes of gastric cancer are:

1. Environmental factors The obvious difference in incidence rates in different countries and regions indicates that it is related to environmental factors. The most important cause of gastric cancer is dietary factors.

Salt may be one of the exogenous factors that induce gastric cancer. Countries where residents consume more salt also have a higher incidence of gastric cancer. Nitrosamine compounds have successfully induced gastric cancer in animals. Smoked fish contains more 3,4-benzopyrene; moldy food contains more fungal toxins; rice is coated with talcum powder after processing, and its chemical properties and structure are similar to asbestos fibers. All of the above substances are considered to be carcinogenic.

2. Genetic factors: The incidence of gastric cancer is higher in some families. Some data show that gastric cancer occurs more often in people with blood type A than in those with blood type O.

3. Immune factors: People with low immune function have a higher incidence of gastric cancer. This may be due to immune dysfunction in the body, which reduces the immune surveillance of cancer, and has a certain significance in the occurrence of gastric cancer.
