. In a large multicenter case–control study of patients with breast cancer from 30 countries, breast-feeding for 12 months or more was associated with a reduced risk of breast cancer of 4.3% (
. In our study, we found no association between breast cancer risk and breast-feeding for women with BRCA2 mutations; the difference between women with BRCA1 and BRCA2 mutations may reflect underlying differences in the pathogenesis of cancers associated with the two genes. However, because our sample of women with BRCA2 mutations was small, it is premature to conclude that a modest reduced risk is not present in this subgroup as well.
