Understanding the main causes of gastric tumors

Gastric tumor is one of the common tumor diseases in my country. In recent years, the incidence rate has gradually increased. So, what is the main cause of gastric tumor? Below we will introduce it in detail, hoping to be helpful to you.

1. Helicobacter pylori (HP) infection: Helicobacter pylori infection in the stomach is one of the important factors for the occurrence of gastric tumors. The World Health Organization has classified Helicobacter pylori as a primary carcinogen for human gastric tumors. The difference in the strains of HP bacteria can lead to differences in the occurrence of gastric tumors. In 1994, Forman of the United Kingdom believed that 35% of gastric tumor cases in developed countries and 85% of gastric tumor cases in developing countries were related to HP infection. Some scholars believe that HP infection may be a synergistic carcinogenic factor for gastric tumors.

2. Genetic factors: Most retrospective survey materials believe that genetic factors play a more positive role in the etiology of gastric tumors, and there is a clear tendency for familial aggregation. It is generally believed that the incidence of gastric tumors in relatives of gastric tumor patients is 4 times higher than that in the control group.

3. Dietary factors: Diet is closely related to the incidence of gastric tumors. In recent years, the incidence of gastric tumors in developed countries in Europe and the United States has been declining. The main cause of gastric tumors is related to dietary factors. Its characteristics are that in the past, food was preserved by smoking (smoked fish, smoked meat) and salting. The food contained a relatively high level of carcinogens, such as benzopyrene, nitrosamines, etc., and high concentrations of salt are considered to be carcinogenic substances. Food fried with high-temperature oil also contains a certain amount of polycyclic aromatic hydrocarbons. In Japan, talcum powder is often used to treat rice, and talcum powder contains carcinogenic asbestos fibers. High-salt foods such as pickled meat, pickled fish, pickled poultry, pickles, bacon, and sausages have also received attention because high-salt foods can damage the gastric mucosa and make carcinogens easily absorbed by the body. Surveys show that salt consumption is significantly positively correlated with gastric tumor mortality. In the diet of some people, protein, fat, certain vitamins and minerals are lacking, which makes the host nutritionally unbalanced, thereby reducing the body's resistance, which is directly or indirectly conducive to the occurrence of gastric tumors.

4. Mycotoxins: Epidemiological surveys have found that mold contamination of grain and food in areas with a high incidence of gastric tumors 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 tumors. Aspergillus versicolor, Aspergillus flavus, Aspergillus nidulans and other molds were detected in gastric fluid, and the versicolor toxins and aflatoxins produced by them can induce gastric tumors in rats.

In addition, the incidence of gastric tumors in people who smoke for a long time is significantly increased. After reading the above introduction to the main causes of gastric tumors, do you know how to stay away from gastric tumors?
