Gastric polyps are categorized into hyperplastic polyps and adenomatous polyps. For hyperplastic polyps with a size of 3mm, removal is generally not necessary and regular clinical observation is sufficient. However, for adenomatous polyps of 3mm, it is recommended to remove the polyp surgically. 1.
