Breast cancer develops when cells in the breast mutate and grow out of control, forming a tumor. Exactly what causes breast cells to mutate isn’t known, but certain factors can increase the risk of this happening. Aging and genetics are the biggest contributors to a woman’s breast cancer risk.

Other factors that may increase a woman’s risk for developing breast cancer include:

  • Obesity
  • Breast density
  • Menstrual history
  • A sedentary lifestyle
  • Heavy drinking
  • Previous medical treatments
