Flat intestinal polyps still have the possibility of becoming cancerous. Usually, polyps with small bases and tips are less likely to become cancerous, while polyps with wide bases are more likely to become cancerous. 1. Small base polyps: Small base polyps with tips are usually benign and less likely to become cancerous, but cannot be absolutely excluded. 2. Larger base polyps: Larger base polyps, which are usually flat in shape, have a relatively high rate of cancer, and if there are signs of enlargement, or signs of ulceration and infection, the possibility of cancer is higher. If you find any discomfort in your intestines, you should go to a regular hospital as soon as possible and have a colonoscopy under your doctor’s guidance. If the colonoscopy reveals flat polyps in the intestines, choose the appropriate surgical plan under the doctor’s advice, remove them as soon as possible, and do the pathological examination to exclude the possibility of cancerous changes of polyps.
