A high-fat diet; Not eating enough fiber; Smoke ; Fat. In some people, genetic factors cause the cells of the colon to multiply more than normal. When this happens in the colon, the person will develop colon polyps. When it occurs in the rectum, the patient will have an anorectal polyp. Thus, a person is more likely to develop colon polyps if he or she has the following genetic conditions:

Sigmoidoscopy: A shorter version of the colonoscope called a sigmoid is used to examine the limited portion of the colon. If polyps are found, the doctor will have to perform an endoscopy to remove them. Virtual colonoscopy: This is a non-invasive procedure in which a doctor uses imaging methods to examine it, which may include X-rays, CT scans, or MRI scans.

Resection of the colon and rectum: This is a total surgical removal, needed only when a person has severe disease or cancer. After the polyp is removed, the doctor will send the sample to a laboratory for testing, where specialists will check for cancer. A pathologist is an expert in analyzing tissue samples who will examine polyp tissue under a microscope to see if the structure is benign or precancerous. These results will form the basis of the recommended interval for the next colonoscopy.
In people who already have polyps or colon cancer, the doctor may prescribe aspirin and coxibs (COX-2 inhibitors) to stop new polyps from forming. For people with a family history of colon polyps, genetic counseling is recommended to prevent the development of lesions.
