About the Ontario Breast Screening Program
 

The Ontario Breast Screening Program (OBSP) is a province-wide, organized breast screening program that provides high-quality breast cancer screening to two groups of women:

  • women aged 50 to 74 who are at average risk for breast cancer with mammography every two years
  • women aged 30 to 69 years who are identified as being at high risk for breast cancer with annual mammography and breast magnetic resonance imaging (MRI) screening

Go to OBSP Screening Appointments and Locations to find out how to make an appointment or to search for OBSP locations near you. Talk to your healthcare provider about regular breast cancer screening.

Studies show that regular mammograms for women aged 50 to 74 years reduce the risk of dying from breast cancer.

Women are encouraged to get screened through the OBSP because an organized screening program offers these important benefits:

  • high-quality mammograms in sites accredited by the Canadian Association of Radiologists
  • well-developed quality assurance at each site
  • inviting women to participate in screening
  • a reminder letter when it is time to return for next screening mammogram. Usually, this is every two years. Women over the age of 73 do not receive a reminder letter.
  • notifying participants and primary care providers of screening results
  • help to set up extra tests or referrals if your results suggest that they are needed
  • tracking participants throughout screening process
  • evaluating program quality and performance

OBSP Screening for Women at High Risk

The OBSP screens women aged 30 to 69 years who are identified as being at high risk for breast cancer. The OBSP High Risk Screening Centres:
  • Facilitate referrals for genetic assessment for women who may be at high risk for breast cancer (if appropriate)
  • Offer annual screening mammography and breast magnetic resonance imaging (MRI) for women who have been identified to be at high risk for breast cancer
  • Facilitate follow-up breast assessment services for women who require extra tests
