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

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 pass the mammography within ten days of the start of your period or when your breasts are less sensitive. You can take two Tylenol 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



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.

Approximatively 15 minutes

Mammographie numerique programme quebecois de depistage du cancer du seinBreast 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 (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 submit to further tests. 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.

Occasionally you might be asked to submit to some of the following additional tests to determine the exact diagnosis. Of course, you will not have to pass all these tests, but only those required by your particular situation.

Do not worry unduly as, most of the time, the additional examinations confirm that there is no cancer. These complementary exams are conducted to ensure that everything is normal.

These additional tests may include:

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

This exam is used primarily to determine if there are cysts in the breast. Some designated private screening centres (CDD), like Radiologie LaSalle, can offer ultrasound exams (not covered by the RAMQ).

Breast MRI, magnetic resonance
Uses a magnetic field. It is indicated in combination with mammography in patients at high risk of cancer. Or, exceptionally, 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.
