BRCA1 carriers, in particular, were also more likely to be also diagnosed with an ovarian cancer themselves (ORBRCA1 vs non‐BRCA: 28.02 [10.72–73.29] and ORBRCA2 vs non‐BRCA: 8.11 [1.87–35.24]) than non‐BRCA patients (eTable 6 in Data Supplement 1, Supporting Information). This evidence concerns the gene BRCA1 and ovarian carcinoma.
