High-Risk Breast Cancer Screening at a Glance
What:
Ontario Breast Screening Program (OBSP)
Who:
Women aged 30 to 69 who have been confirmed to be at high-risk for breast cancer based on the following 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 (less than or equal to) 25 per cent lifetime risk of breast cancer - must have been assessed using either the IBIS or BOADICA risk assessment tools, preferably at a genetics clinic.
- Have received chest radiation before age 30 and at least eight years previously
When:
Annually or determined by healthcare team.
How:
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 30-69 who are at high-risk for breast cancer will improve their quality of care, ensuring they receive the benefits of screening and promoting the early detection of breast cancer.
