Breast cancer screening and prevention

What you need to know about breast cancer, including when and where you should get screened and tips to help reduce your risk.

Why you should screen

When breast cancer is caught early:

  • most women (90%) recover fully after treatment
  • your cancer is less likely to spread
  • you may have more options for treating your cancer

Mammograms are the best way to find breast cancer early. If you need treatment, your doctor will discuss options with you.
