What factors are the causes of gastric cancer

Among the many malignant tumors in China, gastric cancer is one of them. However, although many people know about diseases such as gastric cancer, they know very little about the causes of gastric cancer . Therefore, they are unable to do a good job in preventing gastric cancer. Next, let's learn about what factors cause gastric cancer.

1. Dietary factors: Diet is one of the causes of gastric cancer. According to surveys, high concentrations of salt, such as benzopyrene and nitrosamine, are considered to be the main substances that promote gastric cancer. In the diet of some people, protein, fat, certain vitamins and minerals are lacking, which makes the host nutrition unbalanced, thereby reducing the body's resistance and directly or indirectly contributing to the occurrence of gastric cancer.

2. Smoking and drinking: The incidence of gastric cancer in people who smoke for a long time is significantly increased. The longer the smoking period, the more gastric cancer will occur. Smoking has carcinogenic and cancer-promoting effects on the stomach. Long-term drinking is closely related to the causes of gastric cancer.

3. Chronic gastritis. Gastric cancer is closely related to chronic gastritis, especially atrophic gastritis. The incidence of this type of gastric cancer is related to the severity of atrophic gastritis and the length of medical history. Due to atrophic gastritis, the function and structure of the mucosa are abnormal, the free acid in gastric juice decreases, and the bacteria in gastric juice increase, which increases the synthesis of nitroso compounds. Nitroso compounds have been proven to cause gastric cancer.

The above factors are all causes of gastric cancer to a certain extent. I hope you can understand them. While preventing gastric cancer, you should also pay more attention to these aspects.
