The CIBC Breast Diagnostic Assessment Unit (DAU) at The Scarborough Hospital (TSH) provides access to screening, assessment, diagnosis and treatment for all breast abnormalities. We strive to provide a warm and welcoming environment that respects the need for dignity and privacy. Information and resources at the Breast DAU are available in multiple languages.

TSH is home to a collaborative breast reconstruction program involving both plastic and breast surgeons. We are the only community hospital in Ontario to perform specialized microsurgery to reconstruct the breast using the patient’s own tissue. Traditional reconstruction methods are also available.

Patients who are found to have clinical or imaging abnormalities are supported by a specially-trained Breast Nurse Navigator, while ongoing contact and communication is maintained with their primary care physician.

What We Offer

  • Digital mammography
  • Breast ultrasound
  • Breast MRI
  • Stereotactic core biopsy
  • Ultrasound guided core biopsy
  • Fine needle aspiration
  • Sentinel node biopsy

What To Expect

The Breast Diagnostic Assessment Unit (DAU) accepts patients who have been referred by their primary care physician, or who are referred through OBSP.

Patients are screened using state-of-the-art digital mammography units that are accredited by the Canadian Association of Radiologists. All abnormalities are rapidly followed up with additional imaging and, if necessary, a biopsy. In some cases, consultation with a breast surgeon is arranged to determine a plan of care.

Health Care Team

Breast Nurse Navigator

The Breast Nurse Navigator is an integral member of the health care team with specialized training in breast health. She serves as a liaison to help patients and families navigate the health care system in a timely manner.

The Breast Nurse Navigator provides individualized teaching, information and supportive care during diagnosis and treatment. She works closely with all members of the Breast DAU to ensure patients receive high quality care. A dedicated telephone line is available for patients to call the Breast Nurse Navigator with questions or concerns.


Our team of highly skilled mammography and ultrasound technologists use digital equipment to acquire detailed images and views of the breast for the radiologists to interpret. Technologists also assist the radiologists with image guided biopsies.


Our dedicated radiologists have direct access to digital images, which they can immediately interpret and report on, thus expediting the time to diagnosis and treatment. Radiologists also perform either stereotactic or ultrasound guided breast biopsies.

Breast Surgeons

Our surgeons in the Breast DAU are specialists in breast health. Patients are referred to one of our surgeons for further assessment and treatment of benign conditions, as well as breast cancer.

The following professionals are available if required:

  • Medical and/or Radiation Oncologists
