Colon Cancer Screening Program

The Colon Cancer Screening Program at National Jewish Health combines the expertise of specialists in our Division of Gastroenterology and the Division of Oncology

Early detection and treatment of cancer leads to higher survival rates. The American Cancer Society and The American College of Gastroenterology recommend that colon and rectal cancer screenings begin at age 45 in average risk patients. They also recommend that this screening be repeated every 10 years. For those at high risk, screening every 5 years or sooner may be recommended.

Average RiskIncreased Risk
  • Age 45 or older
  • No personal history of colorectal cancer
  • No family history or colorectal cancer
  • A personal history of colorectal cancer or adenomatous polyps
  • A personal history of inflammatory bowel disease (ulcerative colitis or Crohn's disease)
  • A strong family history of colorectal cancer or polyps (see "Risk factors for colorectal cancer")
  • A known family history of a hereditary colorectal cancer syndrome such as familial
    adenomatous polyposis (FAP) or hereditary non-polyposis colon cancer (HNPCC)


Colonoscopy is the most sensitive diagnostic test and the only one that treats colon polyps (growths on the surface of the large intestine).

Our expert GI faculty offers high quality, comprehensive GI cancer screenings:

  • We visualize 100 percent of the colon in more than 99.8 percent of our patients.
  • We have a 65 percent Adenoma Detection Rate (ADR) which is significantly above the national benchmark of 25 percent. ADR is the rate at which physicians detect adenomas (benign tumor) during a colonoscopy.              


ACS Guidelines for Colorectal Cancer and Polyps

Beginning at age 45, both men and women should follow one of these testing schedules:

Tests that find polyps and cancer

  • Flexible sigmoidoscopy every 5 years1, or
  • Colonoscopy every 10 years, or
  • Double-contrast barium enema every 5 years1, or
  • CT colonography (virtual colonoscopy) every 5 years1

Tests that primarily find cancer

  • Yearly fecal occult blood test (gFOBT)1,2, or
  • Yearly fecal immunochemical test (FIT) every year1,2, or

1 If the test is positive, a colonoscopy should be done.
The multiple stool take-home test should be used. One test done by the doctor in the office is not adequate for testing. A colonoscopy should be done if the test is positive.
