BRCA Carriers with Ovarian Cancer: Low Risk of Breast Cancer

A new study, which included ICARE participants, found that BRCA1/2 carriers with ovarian cancer have a relatively LOW risk of breast cancer.

The hazard ratio for breast cancer after ovarian cancer compared to no ovarian cancer was 0.18 (95% CI: 0.12-0.27; P<0.0001). This means that getting breast cancer after already having ovarian cancer was MUCH less common.

Why is this important?

  • This means that BRCA carriers have a relatively low risk of breast cancer after ovarian cancer
  • Therefore, risk-reducing mastectomy may not routinely recommended, but may be an option for long term survivors
  • Breast screening is reasonable through breast MRI and mammograms
