UPDATED GUIDELINES: Screen for Colorectal Cancer by Age 45

On Wednesday the 30th of May 2018, updated guidelines for colorectal cancer screening in average-risk adults were published by the American Cancer Society (ACS) in CA: A Cancer Journal for Clinicians.

The new recommendation is that adults aged 45 years and older with an average risk of colorectal cancer undergo regular screening. Options for screening include:

Stool-based tests

  • Fecal immunochemical test (FIT) every year.
  • High-sensitivity, guaiac-based fecal occult blood test every year.
  • Multitarget stool DNA test every 3 years.

Structural examinations

  • Colonoscopy every 10 years.
  • CT colonography every 5 years.
  • Flexible sigmoidoscopy every 5 years.

All positive results on non-colonoscopy screening tests should be followed by a colonoscopy. For more information on colon cancer screening, click here.
