The development of gastric cancer, particularly intestinal-type gastric cancer, is a multi-stage process influenced by various factors. Chronic atrophic gastritis is primarily characterized by the atrophy and reduction of gastric mucosal glands. Consequently, it often accompanies varying degrees of metaplasia in the gastrointestinal mucosal epithelium. Chronic atrophic gastritis features a reduction in B cells of the gastric glands, and the pH value of gastric juice may increase. Hence, the relationship between chronic atrophic gastritis and gastric cancer is significant, as it is considered a precancerous lesion. Therefore, if one has atrophic gastritis, it is crucial to seek timely medical treatment to prevent worsening of the condition.
