Colon Screening


Colon screening can detect polyps and early cancers in the large intestine. This type of screening can find problems that can be treated before cancer develops or spreads. Regular screenings may reduce the risk of death and complications caused by colorectal cancer.

Screening Tests

There are many different tests that screen for colon cancer. Each test can be used alone.

Stool Tests
  • Polyps in the colon and small cancers can cause small amounts of bleeding that cannot be seen with the naked eye. But blood can often be found in the stool.
  • This method checks your stool for blood.
  • The most common test used is the fecal occult blood test (FOBT). Two other tests are called the fecal immunochemical test (FIT) and stool DNA test (sDNA).
  • This test uses a small flexible scope to view the lower part of your colon. Because the test only looks at the last one third of the large intestine (colon), it may miss some cancers that are higher in the large intestine.
  • Sigmoidoscopy and a stool test may be used together.
  • How often: Every 5 years, or every 10 years with a FIT every year.
  • A colonoscopy is similar to a sigmoidoscopy, but the entire colon can be viewed
  • Your health care provider will give you the steps for cleansing your bowel. This is called bowel preparation.
  • During a colonoscopy, you receive medicine to make you relaxed and sleepy.
  • Sometimes, CT scans are used as an alternative to a regular colonoscopy. This is called a virtual colonoscopy.
  • How often: Every 10 years.

There is no single “best test” for any person. Each test has advantages and disadvantages. Talk to your doctor about the pros and cons of each test, and how often to be tested. Which test to use depends on—

  • Your preferences.
  • Your medical condition.
  • The likelihood that you will get the test.
  • The resources available for testing and follow-up.
