Colon cancer-Screening


If you are over age 50, the single most important step you can take to reduce your chances of developing colon cancer is to undergo regular screenings. Not only does screening detect colon cancer in its earliest stages when it is most readily treated, but it can also prevent the disease by identifying abnormal growths, known as polyps, which the doctor can remove before they develop into cancer.

Some of these screening tests are uncomfortable and in some instances you will need to use a laxative beforehand so the colon is completely clean and any abnormal growths can be seen more clearly.

Most commonly recommended methods to screen for colon cancer

How often and when:

Screening method recommended:

Every year beginning at age 50

  • Home fecal occult blood test (FOBT), which you can do at home with a kit that your physician provides.

Every five years beginning at age 50

  • Flexible sigmoidoscopy, in which a thin, flexible tube is inserted into your rectum so the physician can view the lower part of your colon. This will be done in your physician's office.

  • Your physician may also recommend that you combine a FOBT with the sigmoidoscopy.

  • Double contrast barium enema

  • CT colonography (virtual colonoscopy) Every 10 years

  • Colonoscopy, which is similar to the flexible sigmoidoscopy but involves the use of a longer tube to view the entire colon.
