Mammography is a diagnostic screening tool that uses low energy x-rays to examine the breast. A mammography exam, called a mammogram, supports the early detection and diagnosis of breast diseases.

Women aged 50-74 are eligible for a bi-annual screening mammogram provided by the Ontario Breast Screening Program (OBSP). In screening cases, a doctor’s referral is not required.

For patients presenting with new breast symptoms, breast implants or a history of malignant tumours, a physician’s referral is required.
