Breast cancer: facts and figures

A clear picture of the numbers helps put risk in perspective and shows why early detection matters so much.

Breast cancer is the most commonly diagnosed cancer in women worldwide and one of the leading causes of cancer death in women. Yet survival rates keep rising thanks to earlier detection and better treatments.

The numbers that matter

  • About 1 in 8 women will develop invasive breast cancer at some point
  • The risk in men is about 1 in 800
  • The majority of breast cancers are found in women over 50
  • Most women diagnosed with early-stage breast cancer live many years after treatment

Statistics describe populations, not individuals. Your personal risk depends on your history, your genes and your lifestyle — and it can be discussed with a doctor.
