  1. BC breast cancer, OC ovarian cancer
  2. aSeven patients had both breast and ovarian cancer
  3. bThe percentage of patients with each high-risk feature among BC patients. Because of rounding, the total does not equal 100%
  4. cThe percentage of patients with high-risk feature among OC patients
  5. dFamily history of BC and/or OC in ≥1 close blood relatives (includes first-, second-, or third-degree relatives)
