Breast Cancer Screening

The Ontario Breast Screening Program (OBSP) is a province wide, organized breast screening program that provides high-quality screening to Ontario women. Women eligible to be screened through the OBSP include Ontario residents who are 50-74 years of age and have no acute breast symptoms, no personal history of breast cancer, no current breast implants and have not had a screening mammogram within the last 11 months. 

Women over the age 74 can be screened within the OBSP; however, they are encouraged to make a personal decision about breast screening in consultation with their healthcare provider. The OBSP will not recall women over age 74 to participate in the program.  

The OBSP screens women aged 30-60 years at high risk for breast cancer with annual mammography and breast magnetic resonance imaging (MRI) screening every year.
