are sessile polyps cancerous
These polyps do not become cancerous. In this case you can continue your regular screenings, unless you are at an increased risk for colon cancer because of a family history of colon cancer or an inherited polyp syndrome. A sessile polyp doesn't have a stalk. It is mostly a flat growth.hese large polyps sometimes cannot be removed safely during a colonoscopy and may be more likely to develop into cancer. If cancer is found when the colon polyps are examined, you will begin treatment for colorectal cancer. For more information, see the topic Colorectal Cancer.
