Here are some excerpts from the new guidance for colorectal cancer screening by the American College of Physicians (ACP):
- colorectal cancer screening should start at the age of 50 years for people at average risk, and at 40 years (or 10 years before the age of the youngest case of colorectal cancer in a family) for people at high risk
- stool-based tests, flexible sigmoidoscopy, and optical colonoscopy are all acceptable screening options for people at average risk
- the gold standard—optical colonoscopy—is recommended for people at high risk
- screening should be stopped for adults aged over 75 years or who have a life expectancy of less than 10 years
Colorectal cancer screening can lead to harmful outcomes such as perforation, bleeding, and false-negative results.
