American Cancer Society Updates Colorectal Cancer Screening Guideline for Average Risk Adults

September 17th, 2018

The ACS recently updated Colorectal Cancer Screening Guideline using prevailing evidence as well as microsimulation modeling analyses. The new guideline does not prioritize among screening test options. This is because test preferences vary among individuals and the guidelines development committee emphasized that screening rates could be improved by endorsing the full range of tests without preference. Adults born around 1990 have twice the risk of colon cancer and four times the risk of rectal cancer compared with adults born around 1950, who have the lowest risk. In the updated guideline, screening is recommended earlier, starting at age 45 years and may be performed  with either a high-sensitivity stool-based test or a structural (visual) exam, depending on patient preference and test availability.
