As the lifetime risk of breast cancer has increased, early detection methods have become integral in identifying tumors before symptoms develop. According to the American Cancer Society (ACS):

  • A woman currently living in the U.S. has a 12 percent, or 1 in 8, lifetime risk of being diagnosed with breast cancer – compared to a 1 in 11 risk in the 1970s.
  • Breast cancer typically produces no symptoms when the tumor is small and most treatable.
  • Mammography screening can detect tumors 1 to 3 years before they would have been detected if allowed to grow until symptoms develop.

Knowledge of personal risk factors and early screening are the first steps towards a higher probability of survival.

  • Women diagnosed at early stages have a higher five-year relative survival rate. According to the ACS, five-year relative survival ranges from 99 percent for localized disease (confined to the breast) to 23 percent for distant-stage disease (spread to other organs).
  • From 1990 to 2007, death rates decreased by 3.2 percent per year among women younger than 50 and by 2 percent per year for women 50 and older. This decline has been attributed to improvements in treatment and early detection.
