A study that combined 9,856 women from the United States, Europe, Australia, New Zealand, and Canada provided definitive findings as they all had either one or the other BRCA gene.

  • From the beginning around 4,800 of them had either breast cancer or ovarian cancer before the study began.
  • Around 5,000 of the women did not have either type of cancer.
  • They followed these women for the next five years to document the cases of cancer as they occurred or did not.
  • The ages of the women ranged from less than 20 years of age to more than 70 years of age.
  • The group that had BRCA1 had a 72 percent risk of getting breast cancer by 80 years of age.
  • The group that had BRCA2 were 69 percent more likely to get breast cancer by 80 years of age.
  • Women who had BRCA1 genes found their chances of getting cancer from 30 to 40 leveled off.
  • Those with BRCA2 genes leveled off from getting cancer from 40 to 50.
  • Chances for younger women to develop ovarian cancer was low but it rose among women who were in their 40s and 50s.
