These are defined as abnormal growth of tissue in the large intestinal lining. A percentage of these, if not removed, can go onto to become cancerous. Most colon polyps encountered during colonoscopy can be removed, drastically reducing one’s risk of colon cancer and emphasizing the importance of colon cancer screening.
Weaknesses in the muscular layer of the intestinal wall can cause the inner lining to form small, balloon-like pouches that protrude along the intestinal tract. These pouches are known as diverticula and are usually harmless, unless they can get infected, inflamed, or perforate.
