How does gastric cancer form

summary

I got gastric cancer stage 3. I had an operation a week ago, but I still can't get out of bed and walk. I found on the Internet that this kind of advanced disease usually can't live for several years, and she still has ascites and spits blood, which should have spread. Now let's talk about the formation of gastric cancer.

How does gastric cancer form

First: unreasonable diet: long term consumption of moldy grain, moldy food, pickled vegetables, smoked and pickled fish, excessive intake of salt, can increase the risk of gastric cancer. These foods contain high concentrations of nitrate, easily absorbed by the body, in the stomach by bacterial reductase into nitrite, and then combined with amine into carcinogenic nitrite amine. Diet induced gastric cancer is also the most difficult factor to avoid.

Second: Helicobacter pylori infection: its secreted toxin can make gastric mucosal lesions, so we must pay attention to their own health, avoid infection can induce gastric cancer factors.

Third: precancerous lesions: that is, systemic or local diseases and conditions that are prone to malignant transformation, such as chronic atrophic gastritis, adenomatous gastric polyps, residual gastritis, etc.

matters needing attention

Genetic factors are one of the causes of gastric cancer. Epidemiological investigation shows that the incidence of gastric cancer has a tendency of family aggregation, and this kind of population should pay special attention to the prevention of gastric cancer. In addition, the occurrence of gastric cancer is related to diet. If the diet is improper, it will have a great impact on the stomach. Therefore, we must attach great importance to the diet. After all, some foods will lead to cancer. However, there is no need to worry too much. There are tumor suppressor genes in the human body. As long as you eat an appropriate amount of the above food and pay more attention to dietary taboos, you will not induce gastric cancer.
