 10anscancer Breast cancer is the type of cancer most diagnosed in Quebec women. We estimate that one woman out of nine has a chance of developing this cancer during her lifetime. Being a woman and getting older are the two principal risk factors. Having women who have had breast cancer in the family (grandmother, mother, sister, etc.) is also a risk factor, but the majority of women who have breast cancer do not have any in their family. Even if you don’t feel anything, the mammography can find very small changes in your breasts.

The screening mammography is a radiography of the breasts which allows detection of very small lesions which often would not be palpable. Usually, two radiographies of each breast are necessary; a frontal view and an oblique angle.

The breast is compressed to allow 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 a cancer because of frequent mammographies is non existent.

Some women are uncomfortable and feel pain during the compression of the breast. This pain is usually brief and should not be a concern. 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 that the examination be done during the ten days following the beginning of your menstrual cycle or when your breasts are less sensitive.

It is possible that after receiving the result of your mammography, your doctor (or your CDD) asks you to have other exams. This does not necessarily mean that you have breast cancer.

 Mammography is recognized as the most efficient method to detect breast cancer. However, it has its limits. For example, we estimate that in almost 7% of women participating in a breast cancer screening program, the results of the mammography are interpreted as uncertain.

In the vast majority of cases, there is no breast cancer.
For example, in a screening context, the majority of exams done reveal mostly non cancerous lesions.

When a mammography shows abnormal or uncertain signs, additional exams are then necessary to establish an exact diagnostic.

There are many types of exams each one corresponding to a specific need. Of course, you will not have to pass all of these exams, only those relating to your particular condition.

These exams may be:
Clinical exam of the breast palpation of the breasts and the underarms by a doctor
Additional radiographies Additional mammographies in order to determine the nature of the lesion
Ultrasound exam using ulrasounds, mainly to determine if there are cysts in the breast; some private screening centers (CDD) can offer ultrasound exams which may require billing the patient.
cytopuncture or biopsy with a fine needle biopsy of cells with a fine needle where the lesion if palpable in the breast;
Biopsy with a trocar biopsy of tissue with a larger needle in a lesion in the breast;
Surgical biopsy biopsy of a lesion by surgery;
Stereotaxic localisation procedure permitting the insertion of a guide in a non palpable lesion of the breast, with the help of a computer. With this guide in place, the biopsy can then be done in the precise area where the lesion is located.
How to prepare yourself for the complementary exams to the mammography?
As for many women, it is possible that you are worried about having to undergo more exams for the screening of a breast cancer disease. However, the best way to fight the anxiety is to prepare yourself for these exams and to ask for the best possible information.

Here are some suggestions:

Make a list of all the questions you wish to ask your doctor during your visit at his office and during the exam. Do not hesitate to ask the same question more than once if you are not sure that you understood the answer properly. Also, do not hesitate to write down the answers given to you.

If you wish, have someone accompany you to your appointment, your spouse, a friend or your sister. Between the two of you, you will remember more details.

For these exams, do not wear a dress as you will have to remove your clothing down to the waist. A two piece suit will be more practical.

Feel free to talk about your fears and concerns.

Ask how long before you get the results of your exam. There is no sense worrying about the results after 3 days if they are not available for a couple of weeks.

Do not worry too much, most complementary exams show that there is no cancer. These exams are done as an added precaution.


If your breasts are sensitive, it is preferable to avoid coffee, tea, chocolate and colas during the two weeks prior to the exam.

Do not use deodorant, powder, cream or perfume on your breasts or underarms. These products can give false images which can be mistaken for lesions.

For the exam, you will have to remove jewelry, like chains, earings and all other object which could be in the way.
Preparation :
The day of the exam, do not wear powder, cream, perfume or deodorant on the breasts or under the arms. If your breasts are sensitive, it is preferable to avoid coffee, tea, chocolate and colas during the two weeks prior to the exam. Take two Tylenol one hour before the exam.

The consultation request from your doctor.
