H. pylori infection does not mean that you will definitely get gastric cancer in the future, there is a relationship between the two, but there is no inevitability. In fact, the rate of H. pylori infection in China is more than 50%, but the incidence of gastric cancer is far less than that. Most people have no symptoms after infection, and a small number of people have infection triggered by certain factors leading to the occurrence of gastric ulcer, duodenal ulcer, and atrophic gastritis. Gastric cancer usually develops on the basis of chronic atrophic gastritis, intestinal epithelial hyperplasia and atypical hyperplasia. In conclusion, H. pylori positivity is only one part of gastric cancer development, genetic, dietary and environmental factors are also crucial.
