Generally recognized as the best way of detecting polyps, colonoscopy is one of three widely used and recommended screening tests for colon and rectal cancer.
Colonoscopy uses a thin, flexible tube with a light and camera attached to examine the lining of the large intestine (rectum and colon). The procedure can be used to help diagnose abnormalities such as ulcers, polyps, tumors and areas of inflammation or bleeding.
For persons over age 50, the American Cancer Society recommends either:
• a yearly fecal occult blood test, plus sigmoidoscopy once every five years, or
• colonoscopy once every 10 years
Persons with a moderate to high risk of colon or rectal cancer are advised to have more frequent screening. Most at risk are persons who have already had a precancerous polyp removed or who have a close relative diagnosed with colorectal cancer.
Because risk factors, medical and family history vary from patient to patient, Mark Klucka, D.O., Gastroenterologist, advises patients to speak with their physician regarding the frequency with which they schedule a colonoscopy.
“You should follow your doctor’s recommendation. The colonoscopy is a lot easier than it sounds and people should not be afraid of it because it does save lives. The test should be repeated in 7 to 10 years if there are no polyps and no new symptoms,” Dr. Klucka said.
To prepare, it’s necessary to clear the bowels, and many consider this the most difficult part. The colonoscopy itself takes about half an hour and is performed under sedation, usually given intravenously. Even though you’re conscious, you’re likely to be groggy and not remember much of the procedure.
One major advantage of colonoscopy is that when a cancerous or precancerous polyp is detected, it can be removed or biopsied on the spot. Moreover, if results are normal, the procedure may be performed less frequently.
Medicare, Medicaid and most private insurers pay for a colonoscopy once every 10 years for persons who qualify.
