Breast Cancer Screening

The Ontario Breast Screening Program (OBSP) expands its eligibility criteria to include those aged 40 to 49 as of October 9th, 2024.

Ontario Breast Screening Program (OBSP) 40 to 49 Expansion

Effective on October 8, 2024 people in Ontario ages 40 to 49 who are otherwise eligible can self-refer for breast cancer screening in the Ontario Breast Screening Program (OBSP). Eligible people ages 40 to 49 no longer require a referral from a primary care provider to access breast cancer screening through the OBSP.


Making an informed decision about breast cancer screening

People ages 40 to 49 should make an informed decision about whether breast cancer screening is right for them. The OBSP encourages people to speak with their doctor, their nurse practitioner or a Health811 navigator about their personal risk for breast cancer, the potential benefits and potential harms of breast cancer screening, and what matters most to them in taking care of their health.


Resources available to support people ages 40 to 49

People ages 40 to 49 can talk to their doctor, their nurse practitioner, a Health811 navigator or, in certain communities, a prevention specialist to help them make an informed decision about whether breast cancer screening is right for them. For more information about breast cancer screening for people ages 40 to 49, general information about the OBSP, and how to make an appointment for screening, visit Breast Cancer Screening for People Ages 40 to 49: What You Need to Know.
