Research Progress on the Relationship Between Helicobacter Pylori Associated Chronic Atrophic Gastritis and Gastric Cancer

Helicobacter pylori(HP) associated chronic atrophic gastritis (CAG) is known to be a precancerous lesion of gastric cancer, and can act on gastric carcinogenesis through a variety of factors, but the specific mechanism of action is not yet clear. In this paper, we review the research progress of the mechanism of HP associated CAG in the development of gastric cancer to provide reference for clinical medical staff.
