Scattered bulging erosions of the gastric sinus have the potential to become cancerous, but the chances are low. A pathological tissue biopsy is needed to make a definitive diagnosis, and it is important to follow medical advice while treating erosive lesions as they occur and to review them regularly.
Erosion of the gastric sinus has the potential to progress to gastric cancer, but the chances are low because there is a <1% chance that a gastric ulcer will progress to gastric cancer. The preferred site for gastric cancer is the gastric sinus, accounting for roughly 58% of cases, followed by other sites such as the cardia and body of the stomach. The most important thing is that the patient has a good chance of being able to get to the bottom of the ulcer.
In general, the presence of scattered raised erosions of the gastric sinus on gastroscopy has a chance of becoming cancerous, but the chances are low. If the erosion is simple, it may be acute gastritis, often with edema around the erosion, mostly due to a history of heavy drinking and stress, and if the erosion is accompanied by an ulcer, it may be a gastric ulcer, mostly with H. pylori infection. Therefore, a pathological tissue biopsy is required for a definitive diagnosis, and cannot rely solely on medical history or microscopic naked eye changes.
