Definition
By Mayo Clinic staffStomach polyps are masses of cells that form on the inside lining of your stomach. Stomach polyps, also called gastric polyps, are rare.
Stomach polyps typically don't cause any signs or symptoms. Stomach polyps are most often discovered by accident, such as when your doctor is examining you for some other reason.
If your doctor discovers you have stomach polyps, treatment advice is determined by the type of stomach polyps you have. Most stomach polyps don't become cancerous, but certain types may increase your risk of stomach cancer in the future. For this reason, some stomach polyps are removed and others may not require treatment.
