Introduction to the three most common causes of gastric cancer

As the mortality rate of gastric cancer in China continues to increase, many people have begun to pay attention to the causes of gastric cancer . So what are the causes of gastric cancer? Here are some common causes of gastric cancer.

In general, the common causes of gastric cancer are:

1. Chemical substances such as nitrosamines: Experiments have shown that nitrosamine compounds of various structures can cause gastric cancer in animals. Investigations in areas with a high incidence of gastric cancer have found that the content of nitrates and nitrites in drinking water and food is significantly higher than that in areas with a low incidence. Under suitable pH values ​​or the action of bacteria, nitrates and nitrites can synthesize carcinogenic nitrosamine compounds in the human stomach. Some pickled meats, fish, poultry, and vegetable foods, as well as foods treated with nitrites such as sausages, ham, luncheon meats, and pickled meat products also contain a small amount of nitrosamine carcinogens. In addition, there are reports that some cheeses, milk, flour, beer, and other alcoholic beverages at home and abroad can also be detected. Nitroso compounds are used as solvents, lubricants, rust inhibitors, etc. in industry, and as pesticides, herbicides, etc. in agriculture, and can be exposed to occupational causes. This is currently a common cause of gastric cancer.

2. Mycotoxins: Epidemiological surveys have found that mold contamination of grain and food in areas with a high incidence of gastric cancer in my country is quite serious. The detection rate of molds and their toxins in fasting gastric fluid of patients with chronic gastric disease in high-incidence areas is significantly higher than that in areas with a low incidence of gastric cancer. Aspergillus versicolor, Aspergillus flavus, Aspergillus nidulans and other molds have been detected in gastric fluid. The versicolor toxins and aflatoxins produced by them can induce gastric cancer and are also common causes of gastric cancer.

3. Smoking and drinking: Long-term smokers have a significantly higher incidence of gastric cancer. The longer you smoke, the more gastric cancer you will get. Smoking has a carcinogenic and cancer-promoting effect on the stomach. Long-term drinking has a synergistic and cancer-promoting effect with other factors that cause gastric cancer.

The above is an introduction to the common causes of gastric cancer. I believe everyone has some understanding of the causes of gastric cancer. For more questions about the causes of gastric cancer, you can consult our online experts, who will give you detailed answers.
