Experts agree that mammograms are the best screening test for people at average risk of breast cancer. Guidelines for when to start having mammograms and how often to have them vary from province to province.
You should discuss the benefits and harms of mammograms with your healthcare provider. They can help you decide when to start and how often to have a mammogram.
For people who are at average risk for breast cancer, the Alberta Breast Cancer Screening Program Clinical Practice Guidelines recommend the following:
The screening tests for breast cancer include:
This is an X-ray of the breast that can often find tumours that are too small for you or your doctor to feel. Most of the ones done today are digital mammograms. They record images of the breast in an electronic file.
Tomosynthesis is a newer form of mammogram that creates a 3-dimensional image of the breast.
CBE is not a replacement for a mammogram, and may be done as part of a physical examination. During this test, your doctor will carefully feel your breasts and under your arms to check for lumps or other unusual changes. Talk to your doctor about whether to have this test.
Breast awareness. Breast awareness is the practice of becoming familiar with your breasts. If you notice any changes in your breasts or you have concerns, talk to your healthcare provider rightaway.
An MRI may be recommended by the doctor for people who have a high risk of breast cancer. This includes anyone who tests positive for the BRCA1 or BRCA2 gene and/or have a strong family history of breast cancer.
