Abstract excerpt

We conducted a study to determine whether the risk of breast cancer associated with oral contraceptive (OC) use is higher in women with BRCA1/BRCA2 mutations than in other women by examining whether breast cancer patients with these mutations were more likely than breast cancer patients without mutations in BRCA1/BRCA2 to have used OCs. We tested for BRCA1 185delAG and 5382insC and BRCA2 6174delT mutations in a...
