The
Ontario Breast Screening Program (OBSP) provides high-quality breast screening for eligible people.
Average Risk
Screening People Ages 40 to 49:
The OBSP encourages women, Two-Spirit people, trans people and non-binary people ages 40 to 49 to make an informed decision about whether breast cancer screening is right for them. Most people in this age group who decide to get screened for breast cancer should be screened with mammography every 2 years.
Screening People Ages 50 to 74:
The OBSP recommends that most eligible women, Two-Spirit, trans and non-binary people ages 50 to 74 get screened with mammography every 2 years.
High Risk
The OBSP recommends that women, Two-Spirit people, trans people and non-binary people ages 30 to 69 who meet the High Risk OBSP eligibility criteria get screened every year with both mammography and breast magnetic resonance imaging (MRI) (or screening breast ultrasound if MRI is not medically appropriate).
