Mammography is a specialized examination for early cancer detection and diagnosis of other common breast diseases. In addition to mammography, if necessary, we offer a breast ultrasound Service.

Screening mammograms are covered by the RAMQ beginning at age 40:
- With a doctor's prescription for women aged 40 to 49 or age 70 and over;
- With an invitation letter from PQDCS or a doctor's prescription for women aged 50 to 69.

Diagnostic mammograms for women of all ages with a prescription from a doctor are also covered by the RAMQ.

Also offered
- Breast ultrasound
- Ultrasound-guided cyst puncture

The exam process

Following your registration, the technologist performs your digital Mammography. During the exam, the breast is compressed to reduce its thickness to obtain a precise image and to reduce the quantity of radiation required.

The risk of developing a cancer as a result of repeated mammograms is practically nonexistent.

Some women may feel some sensitivity to breast compression. It is usually brief and transitory and you should not worry.

Duration of the exam

Approximatively 15 minutes

Exam types and costs

Digital screening mammography or additional mammography:

Breast ultrasound

  • No fees, covered by the RAMQ.
  • 5$ for each copy of report for your personal file - 10$ for each copy of the images on CD for your personal file


If your breasts are sensitive it is preferable to avoid coffee, tea, chocolate and colas during the two weeks prior to the exam. For the same reason, It is recommended to have the mammography within 10 days of the start of your period or when your breast are less sensitive. You can take two Acetaminophen (Tylenol*) or Ibuprofen 1 hour before the exam.

Do not use deodorant, powder, cream or perfume on your breasts and armpits. These products cause false images that can be mistaken for lesions.

We suggest you wear two-piece clothing as you only need to remove the top to complete the exam.

To reduce any anxiety which may be related to the mammography exam or complementary tests, we suggest to:

Make a list of all the questions you want to ask your doctor. Feel free to share openly your fears and concerns. We encourage you to write down the answers we give you.

If you wish, you may be accompanied by another person as two people often retain more elements and details.

Ask when you should be getting your exam results so as not to worry unnecessarily.



The most commonly diagnosed cancer among women in Quebec.

Breast cancer is the most commonly diagnosed cancer among women in Quebec. It is estimated that one woman in nine may develop this kind of cancer during her life. Being a woman and getting older are the two main risk factors. Having a family history of breast cancer (maternal, grandmother, mother, sister, etc.) is also a risk factor, but the majority of women do not have a family history of breast cancer. Even if you do not feel anything, mammography can find very small changes in your breasts. Mammography is currently recognized as the most effective method to detect breast cancer.

It is possible that after learning the results of your mammogram, your doctor (or the radiologist) invites you to undergo further testing. This does not necessarily mean that you have breast cancer.

In the vast majority of cases, there is no breast cancer. Indeed, in the context of screening, the majority of examinations reveal more noncancerous lesions.

These additional tests may include:

X-ray images
Taking additional mammograms to clarify the nature of the lesion.

This exam is complementary to mammography. It is use to re-evaluation a given area, or to further look at mammographically dense breasts.

Breast MRI, magnetic resonance
Uses a magnetic field. It is indicated in combination with mammography in patients at high risk of cancer. Or, occasionnally, to assess the extent of a known breast cancer.

Fine needle biopsy
Cell sampling performed with a fine needle in the location where a lesion is found in the breast.

Core needle biopsy
Tissue sampling with a larger needle in a breast lesion.

Surgical biopsy
Sample of a portion of the lesion through surgery.

Stereotactic localization
Allows placement of a wire in a non-palpable lesion with computer guidance. This wire serves as a guide for surgical removal at the precise area where the lesion is located.
