OBSP Screening for Women at High Risk
 

The Ontario Breast Screening Program (OBSP) screens women at high risk for breast cancer. There is evidence that annual screening with breast magnetic resonance imaging (MRI) in addition to mammography (MM) benefits women at high risk.

The introduction of combined MM/MRI screening into the OBSP for women aged 30 to 69 who are at high risk for breast cancer will improve their quality of care, ensuring that they receive the benefits of screening and promoting the early detection of breast cancer.

Who is eligible for high risk breast cancer screening?

Quick Facts

Less than 1% of women in the general population are estimated to be at high risk for breast cancer.

Women at high risk have a greater estimated lifetime risk of developing breast cancer (up to 85%) than the general population (10-12%).

Women at high risk develop breast cancer at an earlier age and their breast cancers tend to be more aggressive than breast cancers diagnosed in women at average risk.

Women are eligible for the OBSP's high risk screening program if they have no acute breast symptoms, are 30 to 69 years of age and meet one of the following risk criteria:

  • Are known to be carriers of a deleterious gene mutation (e.g., BRCA1, BRCA2)
  • Are the first degree relative of a mutation carrier (e.g., BRCA1, BRCA2) and have declined genetic testing
  • Are determined to be at ≥ 25% lifetime risk of breast cancer -- must have been assessed using either the IBIS or BOADICEA risk assessment tools, at a genetics clinic
  • Have received chest radiation treatment (not chest x-ray) before age 30 and at least 8 years previously.
