Women who have children, particularly early in life, have a lower lifetime risk of breast cancer compared with women who do not. Now, researchers have identified a gene expression pattern in breast tissue that differs between post-menopausal women who had children and post-menopausal women who did not. The results will help scientists understand why pregnancy reduces breast cancer risk.
