There is no specific statistics on the chance of cancerous transformation of erosive gastritis. The chance of cancerous transformation is relatively high, but it is related to the patient’s physical condition and the severity of the disease. Erosive gastritis is a kind of gastric mucous membrane erosion disease that occurs in the gastric sinus area, which may be caused by Helicobacter pylori infection and excessive secretion of gastric acid, and Helicobacter pylori itself has a close relationship with gastric cancer, therefore, erosive gastritis also has a certain chance of becoming cancerous, but there is no accurate clinical data on the chances of becoming cancerous. Although erosive gastric sinusitis has a certain chance of becoming cancerous, but if you can take effective treatment in time, you can often reduce the chance of becoming cancerous. It is recommended to go to the hospital in time, and cooperate with the doctor to take relevant examinations, such as gastroscopy, Helicobacter pylori test, etc., to make a clear diagnosis, and then cooperate with the doctor to take treatment.
