Breast cancer screening in Canada: 2021/2022

About this section

Organized breast screening programs are available in most provinces and territories across Canada. The programs screen individuals who are asymptomatic (no signs or symptoms of breast cancer present) and at average risk for breast cancer. Where organized screening programs are not available, screening services may be accessed opportunistically (outside the organized program) through a primary care provider (PCP). This section describes breast cancer screening programs, guidelines, and recruitment methods in provinces and territories across Canada.
