Breast Cancer Screening Guidelines

Why get screened?
-
Screening mammograms are the best way to find breast cancer early, when treatment may work better.
-
About 1 in 7 women in Alberta will get breast cancer during their lifetime. Regular screening mammograms are the best way to find breast cancer early, when treatment may work better. Mammograms detect possible signs of breast cancer before experiencing symptoms. They are used to detect an abnormality before it can be felt. They can also be used in conjunction with ultrasound if a new lump is present.
Who should get screened?
-
If you’re 45 to 74 years of age, start making mammograms part of your regular health routine. The risk of breast cancer increases as you get older.
Follow these guidelines to know when to get screened:
-
Women younger than 45: Generally, screening mammograms are not performed before the age of 45. Talk to your healthcare provider if you’re concerned about having an increased risk of breast cancer.
-
Women 45 to 74: Breast cancer screening is proven to have the most benefit within this age range. Have a mammogram every 2 years or as decided by you and your healthcare provider. At the age of 45, you are eligible to self-refer with EFW Radiology.

What is a mammogram?
-
A mammogram is an x-ray of the breast performed by a female technologist. Mammograms provide an overall look of both breasts and determine your breast density.
-
They are performed for routine screening, or if you have a concern in your breast. Special views can be obtained as required by our breast imaging specialists.
What happens during a mammogram?
Once you're in front of the mammography unit:
• Your breast will rest on a plastic plate adjusted for height
• A second plate will press down on your breast to provide the compression. Spreading out the breast tissue makes it easier to see small abnormalities
• X-rays will be taken from the top and sides of each breast
Do mammograms hurt?
-
Your breasts need to be compressed to get the best image, which may be uncomfortable or slightly painful (but tolerable). Each compression is very brief. If you normally have tender breasts, it may be more comfortable to have your screening mammogram at least a week before or after your period.
Breast changes do not always mean you have breast cancer. If you notice these changes, see your healthcare provider right away:
• a lump in your breast or armpit
• nipple turned inward, if it isn’t usually
• crusting, bleeding or a rash on your nipple
• unusual fluid coming from your nipple
• dimpling or thickening of skin in one area of your breast
