The Most Common Types Of Colon Polyps And Polyp Disorders

Carcinomatous Polyps

This type of adenoma is cancerous. Carcinomatous polyps are dangerous, though are also the rarest type, representing about five percent of adenomas found in screenings. Although typically surgically removed with a polypectomy, there is a risk of some of the cancer cells being left behind in the colon and spreading to other parts of the body. When this occurs, additional surgery is usually undertaken, especially when the lymph nodes or blood system are involved.
