Mackenzie Health is pleased to provide Mammography for patients with a scheduled appointment.

What is a mammogram?

Mammography is specialized medical imaging test that uses a low-dose x-ray system to see inside the breasts. A mammography exam, called a mammogram, aids in the early detection and diagnosis of breast diseases in women.

PLEASE NOTE: Based on direction from Cancer Care Ontario, those scheduled to receive a COVID-19 vaccine should either have their mammogram completed prior to being vaccinated or should wait six weeks from the date of their last vaccination before proceeding with a mammogram under the Ontario Breast Screening Program. COVID-19 vaccine side effects may include swelling of lymph nodes in the underarms which may result in inaccurate results. If you have a mammogram appointment scheduled within six weeks of your COVID-19 vaccination, please contact Patient Scheduling at 905-883-2004 to reschedule your appointment.

An x-ray (radiograph) is a non-invasive medical test that helps physicians diagnose and treat medical conditions. Imaging with x-rays involves exposing a part of the body to a small dose of ionizing radiation to produce pictures of the inside of the body. X-rays are the oldest and most frequently used form of medical imaging.

Digital mammography, also called full-field digital mammography (FFDM), is a mammography system in which the x-ray film is replaced by electronics that convert x-rays into mammographic pictures of the breast. These systems are similar to those found in digital cameras and their efficiency enables better pictures with a lower radiation dose. These images of the breast are transferred to a computer for review by the radiologist and for long term storage. The patient's experience during a digital mammogram is similar to having a conventional film mammogram.

What is the Ontario Breast Screening Program?

The Ontario Breast Screening Program (OBSP) is a province-wide, organized breast screening program that provides high-quality breast cancer screening that women can access by self-referral.

Women aged 50 to 74 who are at average risk for breast cancer can self-refer for a mammogram at Mackenzie Health every two years using the OBSP.

Patients are not eligible to be in the program, if they:

  • have previously been diagnosed with breast cancer
  • have breast implants
  • are experiencing acute breast symptoms
  • have had a mammogram test within the last year
  • are not a current resident of Ontario.

For more information about OBSP at Mackenzie Health call 905-883-1212 ext. 7255 from Richmond Hill or 905-417-2000 ext. 7255 from Vaughan. Learn more about the Ontario Breast Screening Program and Cancer Care Ontario.

What is a Steotactic Breast Biopsy?

Stereotactic breast biopsy is performed as a non-surgical method of assessing a breast abnormality. Using mammography, a specific type of breast imaging and the use of a low dose of x-rays to locate a breast abnormality. The procedure removes a tissue sample that will undergo an examination under a microscope. It's less invasive than a surgical biopsy, it leaves little to no scarring and can be an excellent way to evaluate calcium deposits or tiny masses that are not visible on ultrasound.

What are some common uses of the procedure?

A stereotactic breast biopsy may be performed when a mammogram shows a breast abnormality such as:

  • A suspicious mass
  • Microcalcifications, which are a tiny cluster of small calcium deposits
  • A distortion in the structure of the breast tissue
  • An area of abnormal tissue change
  • A new mass or area of calcium deposits in a previous surgery site.

If the results show cancer cells, the surgeon can use this information for planning treatment.

Following your appointment, patients are advised to:

  • Avoid strenuous activity for at least 24 hours after your biopsy.
  • Please contact your physician if you experience excessive swelling, bleeding, drainage, redness or heat in the breast.
