A mammography uses X-rays to produce images of the internal breast structure. The exam is used to detect anomalies such as cysts and cancer tumours. The mammography is also used for screening purposes and is part of the Ontario Breast Screening Program.

Mammography exams are done by the Medical Imaging Department.

How to access our services?

  • You must have a referral from your family doctor to get an appointment for this test.

About The Program

Before your appointment

  1. Your family doctor will fax us a request – please make sure that your contact information is accurate so we may call you.
  2. We will call you within 2 to 3 weeks to schedule an appointment, which will take place a few weeks later. Therefore, it could take up to 6 weeks between your doctor’s referral and your appointment at HGH Diagnostic Imaging.
  3. If you had a mammography elsewhere in the past 10 years, please obtain the following from your healthcare provider:
    1. Films or copies of the digital images on a CD or DVD. Ask them to make the CD or DVD DICOM-compatible. Bring to HGH before your appointment.
    2. A copy of the mammography reports.
  4. You will receive a reminder a few days before your appointment.
