Can't find it?

Southlake offers a state-of–the-art Digital Mammography x-ray procedure which has been proven to be effective at diagnosing abnormalities in dense breast tissue, often when abnormalities are still too small to be felt. The technologist will explain the procedure, review the medical history and answer any questions. Each breast will be compressed for only a few seconds. This should not be painful, although it can be uncomfortable. Compression is extremely important as it provides a clearer image of the breast by separating the tissue and also reduces radiation exposure.

The appointment takes approximately 30 minutes.

The Mammography Department is accredited by the Canadian Association of Radiologists (CAR) and offers screening and diagnostic mammograms as well as the Ontario Breast Screening Program.

Screening Mammography

Mammography is the best screening test for most women as it plays an important role in early detection of breast cancers. Women can receive a screening Mammogram in one of two ways:

  • A referral from her Primary Care Practitioner (i.e. Family doctor)
  • Self-referral through the Ontario Breast Screening Program (OBSP)


Diagnostic Mammography

Diagnostic Mammography is used to evaluate a patient with abnormal clinical findings that have been found by the patient or their Primary Care Practitioner.

Ontario Breast Screen Program

Women automatically become part of the Ontario Breast Screen Program (OBSP) when they are referred for a mammogram provided they:

  • Are 50 years of age and older
  • Have not had previous breast cancer
  • Do not have breast implants
  • Are not experiencing acute breast symptoms
  • Have not had a mammogram within the last year
  • Are a current resident of Ontario


The OBSP offers important advantages for women and their primary care practitioners by sending recall and result letters to women, and arranging follow-up services for women if further tests are required. Women who are screened for breast cancer within an organized screening program like the OBSP further benefit by participating in a program that undergoes ongoing quality assurance, program monitoring, and evaluation to ensure that its clients receive high quality screening.
