Screening for breast cancer

Screening means checking for a disease in a group of people who don’t show any symptoms of the disease. Screening tests help find breast cancer before any symptoms develop. When breast cancer is found and treated early, the chances of successful treatment are better.

If you are 50 to 69 years old, have a screening mammography every 2 years.

If you are 40 to 49 years old, talk to your doctor about your risk for breast cancer, along with the benefits and limitations of mammography. The research isn’t clear about the benefits for women in their 40s.

If you are 70 or older, talk to your doctor about how often you should have a mammography.
