High Risk Screening Program

As an OBSP High Risk Screening Centre, we can facilitate referrals for genetic assessments for women who may be at high risk for breast cancer. For women who have been confirmed to be at high risk for breast cancer, we offer annual screening mammography and breast MRIs, and facilitate follow-up breast assessment services for abnormal screens .

Referrals for this program must be made by a primary care provider or other physician.

Other Screening

For patients who require breast screening and do not meet the criteria of the OSBP Program (for example, patients under 50 years old), the Breast Screening clinic offers screening mammograms (with a physician’s or nurse practioner’s referral).
