Comments on colorectal cancer screening across professional organizations

Professional organization	Recommended ages for screening	Other considerations
American College of Gastroenterology (2021)	50-75	Screening after age 75 should be considered on an individualized basis; providers must engage in shared decision making
United States Preventive Services Task Force (2021)	45-75	Screening adults aged 76-85 should be conducted on an individualized basis; do not screen adults age 86 years and above
United States Multi-Society Task Force on Colorectal Cancer (2021)	45-75	Consider discontinuation when persons up to date with screening, who have prior negative screening reach age 75 or have < 10 yr of life expectancy. Persons without prior screening should be considered for screening up to age 85, depending on age and comorbidities.
Canadian Task Force on Preventive Health Care (2016)	50-74	Recommend not screening adults aged 75 yr and older. (Weak recommendation; low-quality evidence)
American College of Physicians (2019)	50-75	Discontinue screening in average-risk adults older than 75 yr or in adults with a life expectancy of 10 yr or less
American Cancer Society (2018)	45-75	Screening adults aged 76-85 should be conducted on an individualized basis; screening discouraged above age 85
