Breast Screening


The Ontario Breast Screening Program (OBSP) provides free, high-quality breast screening to two groups of women:

  • Women aged 50 to 74 with no signs of breast cancer are encouraged to have a mammogram every two years through the OBSP as part of their routine medical care.
  • Women aged 30 to 69 who are identified as being at high risk for breast cancer can receive annual mammography and breast magnetic resonance imaging (MRI) screening through the OBSP.
