Breast feeding can significantly reduce the risk of breast cancer in women who harbor mutations in the BRCA1 gene.
According to recent research, breast-feeding is more effective for BRCA1 mutation carriers than for other women.
Women carrying BRCA1 mutations who breast-fed for more than one year were about 60 percent less likely to have breast cancer than women who never breast-fed.
It is possible to modify the breast cancer risk without having to resort to surgery for BRCA1 mutation carriers.
