Colon Cancer Q & A

What tests check for colon cancer?

A colonoscopy is the most common test performed when screening for polyps or colon cancer.

Before your colonoscopy, you will receive a sedative to keep you comfortable throughout the procedure. Dr. Warman will then use a colonoscope -- a narrow instrument with a camera at its end -- to examine your large intestine.

Dr. Warman will primarily check for polyps, which are precancerous growths, and biopsy or remove those he sees during the procedure. The polyps will be tested after the procedure to make sure they're not cancerous.

While a colonoscopy is the most thorough screening option for colon cancer, Dr. Warman can also offer you alternatives. You can opt for a take-home stool sample kit, for instance. This option allows Dr. Warman to screen you for some colon cancer symptoms and possibly other conditions.

When should I start having tests for colon cancer?

If you don’t have specific risk factors or a family history of colon cancer, you should have your first colonoscopy or stool test at age 50. If Dr. Warman doesn’t find polyps, and if you remain in good health, you may not need another colonoscopy test for ten years.

When you choose to receive testing for colon cancer with a stool test rather than with a more comprehensive colonoscopy, the test must be repeated every year.

People from some ethnic backgrounds should receive more frequent testing. If you're African American or Native American, you may have a higher chance of developing colorectal cancer. Dr. Warman may discuss beginning tests sooner for you than age fifty.

How do I prepare for a colonoscopy?

Your bowel must be cleansed before the procedure so Dr. Warman can get a clear look at your colon. He will give you a prescription for laxatives, or perhaps an enema, to help you prepare. There may also be dietary restrictions to follow, and you may be asked to avoid certain foods, including:

  • Popcorn, seeds, nuts
  • Foods high in fat
  • Uncooked vegetables
  • Whole grains
  • Peas, beans, corn

You should also check with Dr. Warman to see if you should stop taking any of your regular vitamins and medicines before your colonoscopy.
