Stomach polyps are masses of cells that form on the inside lining of your stomach. Stomach polyps, also called gastric polyps, are rare.
Stomach polyps usually don't cause any signs or symptoms. The polyps are most often discovered when your doctor is examining you for some other reason.
Most stomach polyps don't become cancerous, but certain types can increase your risk of stomach cancer in the future. For this reason, some stomach polyps are removed and others are not treated.
