Risk factors with the greatest discrepancies among individuals who had counselling and those who did not were: “...a family history of ovarian cancer” (74.6% counselled and 51.1% not counselled); “...a family history of breast cancer from the dad’s side of the family” (74.6% counselled and 56.7% not counselled); “...a pathogenic variant in the BRCA1 or BRCA2 genes” (88.1% counselled and 53.7% not counselled); and “...have cases of breast cancer in more than one generation” (84.6% counselled and 53.5% not counselled). This evidence concerns the gene BRCA1 and ovarian carcinoma.
