In the crude analyses controlling for age and year of diagnosis, BRCA1 and BRCA2 carriers were more likely than non‐BRCA women to report family history of both breast (ORBRCA1 vs non‐BRCA: 4.00 [2.27–7.05] and ORBRCA2 vs non‐BRCA: 2.23 [1.17–4.26]) and family history of ovarian cancer (ORBRCA1 vs non‐BRCA: 7.53 [3.82–14.82] and ORBRCA2 vs non‐BRCA: 3.62 [1.50–8.71]) (eTable 6 in Data Supplement 1, Supporting Information). This evidence concerns the gene BRCA1 and ovarian cancer.
