Mammography is an exam used for early detection of breast cancer and diagnosis of other more common breast pathologies. In addition to mammography, we offer breast ultrasound exams when necessary.

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
  • Ductography
  • MRI (magnetic resonance imaging) of the breast

 Breast MR is indicated in two specific situations. First, it can help in the screening of breast cancer, in association with mammography. This is for patients with high risk of breast cancer through their lifetime. It includes patients with BRCA-1 and BRCA-2 gene mutation, as well as their first untested first relative. Also, patients with rare disease like Li-Fraumeni syndrome, Cowden syndrome and Bannayan-Riley-Ruvalcaba syndrome, as well as their first degree relative. Women who underwent chest irradiation between the age of 10 and 30 years can also be screened with breast MR. Finally, any women with a risk of 20% or more as determined with different risk assessment models can also be included. Breast MR also have a place in the evaluation of patient who had a recent diagnosis of breast cancer, especially if it is an invasive lobular carcinoma. Exceptionally, breast MR can be useful in the assessment of the extent of the disease in certain women, helping to plan treatment accordingly.

Breast cancer is the type of cancer most often diagnosed in women in Quebec. It is estimated that one in nine women risks developing this cancer during her lifetime. Being a woman and aging are the two main risk factors. Family history of breast cancer (grandmother, mother, sister, etc.) is also a risk factor, but the majority of women with breast cancer do not have a family history of the disease. Even if you do not feel anything, mammography can find very small changes in your breasts. 

A screening mammogram is an X-ray of the breasts to detect small lesions that are often not palpable. Usually, two x-rays are required for each breast: a frontal view and an oblique view.

The breast is compressed to obtain a precise image of the inside of the breast and to reduce the quantity of radiation required by reducing the thickness of the breast. The risk of developing cancer due to repeated mammograms is practically nonexistent.

Digital technology slightly lowers the dose compared to the old analog technology. However, the compression level remains identical and the exam is performed in the same manner. On the other hand, because the images are digital, the total duration of the exam decreases.

Some women experience discomfort or pain when the breast is compressed. This is usually brief and temporary and should not be a cause for concern. If your breasts are sensitive, it is best to avoid consuming coffee, tea, chocolate and soda during the two weeks prior to the exam. For the same reason, it is recommended that the mammogram be done within ten days after the start of your menstrual period or when your breasts are less sensitive.

Mammography is currently recognized as the most effective method to detect breast cancer. In addition, digital technology offers a little more detail than analog technology. However, it also has its limits. Indeed, it is estimated that in about 7% of participants in a breast cancer screening program, the mammography results are interpreted as uncertain.

In the vast majority of these cases, there is no breast cancer. In fact, in the screening context, the majority of exams reveal non-cancerous lesions.

When a mammogram shows abnormal or uncertain signs, it is necessary to perform further tests to establish an exact diagnosis.

It is possible that after seeing the results of your mammogram, your doctor (or your CDD) will ask you to do further exams. In such a case, this does not necessarily mean you have breast cancer.

There are various types of exams, each corresponding to a specific need. Of course, you will not have to undergo all these tests, only those required in your particular situation.

These additional tests may include :
X-ray images Additional mammograms to clarify the nature of the lesion.
Exam using ultrasound Primarily to determine if there are cysts in the breast. Some designated private screening centres (CDD), like ours, can offer ultrasound exams for a fee.
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.


Upon arrival, our staff welcomes you to check-in for your exam on the ground floor.

You will then be sent to the mammography waiting room on the 2nd floor.

The exam usually takes about 15 minutes, involves 4 radiographs and requires compression for a few seconds on each breast. This helps to spread the gland and get an accurate picture of structures inside the breast. Occasionally, the exam is supplemented by other radiographs, if necessary.


Preparation :

If your breasts tend to be sensitive, it is best to avoid coffee, tea, chocolate and soda during the two weeks prior to the exam. You can take two Tylenol 1 hour before the exam.

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

At the time of the exam, you will need to remove your jewelry, such as chains and earrings, and anything else that could interfere with the exam.

How to prepare for additional exams: Like many women, it is possible that you are worried about the thought of undergoing exams related to the detection of breast disease. However, it is known that the best way to combat anxiety is to prepare for these exams and get the best, most complete information possible on the subject.

Here are some suggestions on how to do so:

Make a list of all the questions you would like to ask at your doctor's appointment and during your additional exams. Do not hesitate to ask the same question more than once if you are not sure you have fully understood the answer. Likewise, feel free to note the answers that you receive.

If you wish, bring along another person, whether it is your spouse, a friend or a sister. Two people will find it easier to remember more information and details.

When you come to take additional exams, avoid wearing a dress, because you will have to undress above the waist. A two-piece outfit is more practical because you only need to remove the clothing on the top.

Do not hesitate to openly discuss your fears and concerns.

Ask how long you will have to wait for results of your exam(s). After all, there is no point in worrying after three days if the results won't be available for two weeks!

Do not worry too much. Most of the time, further tests show that there is no cancer. These exams are performed to ensure that everything is normal.
