1. Screening for women at average risk, age 50 and over.

Evidence shows that regular mammograms for women age 50 and over are the most effective way to detect breast cancer early.

Your chances of getting breast cancer increase as you get older. More than 80% of breast cancers are found in women over 50 years old, and most women diagnosed with breast cancer have no family history of the disease. Regular mammograms can help to find breast cancer when it is small and hard to detect.

2. Screening women at high risk of developing breast cancer, age 30 to 69.

For women between the ages of 30 and 69 at high risk of breast cancer, the chances of getting breast cancer are two to five times higher than in the general population. The risk of getting cancer can be as high as 85% if you have certain genetic mutations that are linked with breast cancer like BRCA1 and BRCA2. It's important to be screened for breast cancer if you are at high risk of developing the disease.

How do I know if I am at high risk of developing breast cancer?

Confirmation of high risk is usually established through a breast cancer assessment that identifies your lifetime risk, or through genetic testing. For most women, high risk is linked to a family history of breast or other cancers.

Which women between the ages of 30 to 69 are at risk of developing breast cancer?

If you are between the ages of 30 and 69 and identified by a physician as high risk for breast cancer, it is recommended that you have yearly screening using both a mammogram and Magnetic Resonance Imaging (MRI).

Your family doctor or nurse practitioner will refer you to an OBSP Navigator to book your screening services.
