Chronic gastritis, particularly when caused by Helicobacter pylori infection, has been identified as a significant risk factor for the development of gastric cancer. The chronic inflammation associated with this condition can lead to changes in the stomach lining, including atrophy, metaplasia, and dysplasia, which are precancerous conditions. The World Health Organization (WHO) has classified Helicobacter pylori as a Group 1 carcinogen, indicating a definite link between the bacteria and cancer.
