Analysis of the causes of gastric cancer

As a common malignant tumor in China, the incidence of gastric cancer ranks first among all kinds of tumors. What are the causes of gastric cancer ? Let's ask experts to talk about the causes of gastric cancer.

The currently recognized causes of gastric cancer are:

(I) Environmental factors. The obvious differences in incidence rates in different countries and regions indicate that they are related to environmental factors, the most important of which is dietary factors.

Salt may be the main cause of exogenous gastric cancer. The incidence of gastric cancer is high in countries where residents consume more salt. Nitrosamine compounds have successfully induced gastric cancer in animals. Smoked fish contains more 3,4-benzopyrene; moldy food contains more mycotoxins; rice is covered with talcum powder after processing, and its chemical properties and structure are similar to asbestos fibers. The above substances are all believed to have the effect of causing gastric cancer.

(ii) Genetic factors: The chance of stomach cancer is higher in some families. Some data show that stomach cancer is more common in people with blood type A than in people with blood type O.

(III) Immune factors: People with low immune function are more likely to develop gastric cancer. This may be due to the body's immune dysfunction, which reduces the immune surveillance of cancer, and plays a certain role in the occurrence of gastric cancer.

(IV) Precancerous changes: Precancerous changes refer to certain lesions with a strong tendency to malignant transformation. If such lesions are not treated, they may lead to gastric cancer. Precancerous changes include precancerous conditions and precancerous lesions.

The above is an introduction to the causes of gastric cancer. Understanding and knowing the causes of gastric cancer can help gastric cancer patients better accept the doctor's treatment and recover their health as soon as possible.
