Breast Cancer


Breast cancer is the most commonly diagnosed cancer among Canadian women. It grows in the cells of your breast tissue, which extends all the way up to your collarbone and from armpit to armpit. Breast cancer can affect women of any age, but is most common in women over 50. Screening can spot breast cancer when it’s way too small for you to find on your own.

Screening for Breast Cancer

Whatever your age, you should know what is normal for your breasts and tell your doctor if you notice any changes. Once you reach a certain age, you can also go for screening mammography, a low-dose x-ray. Mammography is the most reliable method of finding breast cancer.

If you are 40 to 49: Talk to your doctor about your risk of breast cancer, along with the benefits and risks of mammography.

If you are 50 to 69: Have a mammogram every 2 years.

If you are 70 or older: Talk to your doctor about how often you should have a mammogram.

Research has shown that women who have mammograms regularly are less likely to have a false positive (when the test results suggest cancer when none is present). We also know that if you do have cancer, it is more likely to be detected when you have mammograms regularly.
