Canada's Draft Breast Cancer Screening Guidelines Should Not Be Be Used
Canada’s draft breast cancer screening guidelines developed by the former Canadian Task Force on Preventive Health Care should not be relied upon. The Task Force’s guideline work was suspended in 2025 following concerns about its processes and methodology. On June 10, 2026, it was replaced by the National Advisory Committee on Preventive Health Services.
It is hoped that updating the breast screening guidelines will be an early priority for the new committee. In the meantime, healthcare providers and Canadians should follow recommendations from the Canadian Society of Breast Imaging, which recommends screening at age 40, supplemental screening for women with Category C and D dense breasts, and continued screening beyond age 74 for those in good health.
These recommendations are more consistent with current evidence and clinical practice than the draft Task Force guidelines.
