Colorectal Cancer Screening Recommendations Summary
Evidence-based recommendations from ColonCancerCheck, Ontario’s colorectal cancer screening program. Also available as a handout: ColonCancerCheck (CCC) Guide to Average Risk Screening with the Fecal Immunochemical Test (FIT) in Ontario.
Screening People at Average Risk of Colorectal Cancer
- Asymptomatic people should be screened with a fecal immunochemical test (FIT) every 2 years. Abnormal FIT results should be followed up with colonoscopy within 8 weeks.
- People ages 50 to 74 without a family history of colorectal cancer who choose to be screened with flexible sigmoidoscopy should be screened every 10 years.
Average risk means:
- People ages 50 to 74 with no first-degree relative (parent, brother, sister or child) who has been diagnosed with colorectal cancer
- People with no personal history of pre-cancerous colorectal polyps requiring surveillance or inflammatory bowel disease (i.e., Crohn’s disease involving the colon, or ulcerative colitis)
