What are the main causes of stomach cancer?

What are the causes of gastric cancer? The incidence of gastric cancer has been on the rise in my country, and the cause of gastric cancer is also the most concerned issue for patients. So, what are the causes of gastric cancer?

Causes of stomach cancer:

1. Genetic factors: Most retrospective survey materials believe that the role of genetic factors in the etiology of gastric cancer is relatively certain, and there is an obvious tendency for familial clustering.

2. Smoking and drinking: Long-term smokers have a significantly higher incidence of gastric cancer. The longer you smoke, the more likely you are to develop gastric cancer. 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.

3. Chronic gastritis: Gastric cancer is closely related to chronic gastritis, especially atrophic gastritis. 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.

4. Dietary factors: Diet is closely related to the incidence of gastric cancer. In recent years, the incidence of gastric cancer in developed countries in Europe and the United States has been declining, which is mainly related to dietary factors. High-salt foods such as pickled meat, pickled fish, pickled poultry, pickles, bacon, and sausages have also attracted attention because high-salt foods can damage the gastric mucosa and make carcinogens easily absorbed by the body.

5. Chemical substances such as nitrosamines: Experiments have shown that nitrosamine compounds with different structures can cause gastric cancer in animals.

6. Mycotoxins: Aspergillus versicolor, Aspergillus flavus, Aspergillus nidulans and other fungi were detected in gastric juice. The mycotoxins and aflatoxins produced by them can induce gastric cancer in rats.

7. Others: Patients with intestinal metaplasia of gastric mucosa, gastric ulcer, and gastric polyps are also at high risk of gastric cancer.

The above are the causes of gastric cancer. I hope everyone can stay away from these risk factors in life and prevent the occurrence of gastric cancer. If you have any questions about the causes of gastric cancer, please consult our online experts.
