Polyps are abnormal growths that arise from the lining of the colon. The majority of
polyps called adenomatous polyps (adenomas) give rise to colon or rectal cancer if not
removed.
The majority are not associated with any symptoms. Some polyps can cause bleeding,
mucous discharge, and changes in bowel habits.
Polyps are diagnosed by either viewing the lining of the colon directly (colonoscopy) or
by x-ray study (barium enema). Colonoscopy uses a flexible endoscope to visualize the polyp
and sedation is often used. The colon can also be examined by using the barium enema x-ray.
Colonoscopy is preferred by most as it allows your doctor to remove polyps at the time of
the procedure. Since polyps occur in 15-20% of Americans, a screening colonoscopy is
recommended for all people 50 years of age and at age 40 for those with a family history
of polyps or colon cancer.
Small polyps can be removed at the time of colonoscopy. Larger polyps may require surgery.
A laparoscopic surgical approach is ideal for large polyps requiring surgery.
