What Factors Can Increase a Woman's Risk of Breast Cancer?


“Breast Cancer Risk in American Women was originally published by the National Cancer Institute.”

 

“Many women are more interested in the risk of being diagnosed with breast cancer at specific ages or over specific time periods than in the risk of being diagnosed at some point during their lifetime.”

 

 

According to the current report, the risk that a woman will be diagnosed with breast cancer during the next 10 years, starting at the following ages, is as follows:

 

  • Age 30 . . . . . . 0.44 percent (or 1 in 227)
  • Age 40 . . . . . . 1.47 percent (or 1 in 68)
  • Age 50 . . . . . . 2.38 percent (or 1 in 42)
  • Age 60 . . . . . . 3.56 percent (or 1 in 28)
  • Age 70 . . . . . . 3.82 percent (or 1 in 26)

The strongest risk factor for breast cancer is age.  A woman’s risk of developing this disease increases as she gets older.
