What are the causes of gastric cancer

The causes of gastric cancer include genetics, environmental factors, dietary habits, Helicobacter pylori infection, chronic gastric disease, unhealthy lifestyle and other aspects. These factors may lead to the occurrence of gastric cancer alone or in interaction with each other.

Genetic factors are one of the potential causes of gastric cancer, and people with a family history of gastric cancer are at a higher risk. Environmental factors include long-term exposure to poor living conditions or pollutants, such as drinking contaminated water, which may also increase the probability of disease. The impact of dietary habits on gastric cancer is particularly obvious. For example, a high-salt diet, long-term consumption of pickled foods, smoked foods, etc., may cause damage to the gastric mucosa and increase the risk of cancer. Helicobacter pylori infection is an important cause of gastric cancer, especially chronic atrophic gastritis, intestinal metaplasia and other pathological processes caused by infection are more likely to deteriorate into gastric cancer. Unhealthy lifestyles such as smoking, alcoholism, irregular diet and long-term mental stress may also induce the possibility of cancer by weakening the immune system or directly damaging the health of the stomach. Chronic pathological changes such as gastric polyps and gastric ulcers may also evolve into gastric cancer if not treated in time.

In order to prevent gastric cancer, it is very important to develop healthy eating and living habits. You should reduce the consumption of pickled and smoked foods, increase the intake of fresh fruits and vegetables, whole grains, and low-fat dairy products, and maintain a balanced diet. Eat three meals regularly and avoid overeating. Quit smoking and limit alcohol, especially avoid drinking on an empty stomach to reduce the risk of stomach damage. If there is a history of gastric cancer in the family or long-term stomach discomfort, regular stomach examinations should be performed, such as gastroscopy screening, Helicobacter pylori testing, etc., to detect potential risks early. Monitoring the development of chronic gastric disease and timely treatment of lesions can also effectively reduce the possibility of gastric cancer.
