Who to screen: asymptomatic adults ages 50-74 at average risk. Do not use this pathway for patients with symptoms, personal history of colorectal cancer or adenomas, inflammatory bowel disease, or first-degree relatives with colorectal cancer.
Test and interval: FIT or gFOBT every 2 years, or flexible sigmoidoscopy every 10 years. The Task Force does not recommend colonoscopy for routine screening.
Stopping: routine screening is not recommended after age 75.
Follow-up: positive stool tests require diagnostic colonoscopy and active recall tracking. Use provincial program workflows.
