Several major common causes of gastric cancer

Gastric cancer is also one of many cancer diseases. Many people may suffer from this disease. So, what is the main cause of gastric cancer ? Next, let's learn about it from the following article.

1. Genetic factors: Most surveys believe that genetic factors play a more positive role in the etiology of gastric cancer, and there is a clear tendency for familial clustering. It is generally believed that the incidence of gastric cancer in relatives of gastric cancer patients is 4 times higher than that in the control group.

2. Chronic gastritis: Gastric cancer is closely related to chronic gastritis, especially atrophic gastritis. The incidence of this type of gastric cancer is related to the severity of atrophic gastritis and the length of medical history. 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. This is also the cause of gastric cancer.

3. Dietary factors: Diet is closely related to the onset of gastric cancer, which can be said to be an undisputed cause 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.

The above are the main causes of gastric cancer. I hope it can help everyone know more about gastric cancer. If you have other questions about gastric cancer, you can contact our online experts to answer your questions.
