About Breast Cancer

Breast cancer is a type of cancer where cells in the breast tissue divide and grow without normal control. It is a widespread and random disease, striking women and men of all ages and races. It is the most prevalent cancer in the world today, with about 1.3 million people diagnosed annually. The exact cause of the disease is unknown, and at this time, there is no cure.

But there is hope. Thanks to heightened awareness, early detection through screening, improved treatment methods and increased access to breast health services, people have a greater chance of survival than ever before.

The Susan G. Komen for the Cure national website,, offers comprehensive information about breast cancer risk factors, early detection and screening, diagnosis and treatment. Developed in conjunction with the Harvard School of Public Health, the site offers a one-stop resource for all the latest information on the disease.

Breast Cancer Risk Factors Table

The table below shows the relative risk of breast cancer for many factors. The relative risk compares the risk of breast cancer for people who have the factor to those who do not.
Factors are grouped based on the strength of the scientific evidence for each risk.

  • Established and probable have the strongest evidence behind them and are recognized as linked (or not linked in some cases) to breast cancer.
  • Possible factors have less evidence behind them; they suggest links to breast cancer but need more study before solid conclusions can be made. 
  • Insufficient or inconsistent factors are backed by few studies or the studies to date show very mixed results, which don't allow comment on any potential link with breast cancer.
