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.
