Is it true that breastfeeding is linked to a lower risk of breast cancer in mothers?
Yes. A reference source states that long-term benefits of breastfeeding for the mother include decreased risk of breast cancer, and several peer-reviewed reviews also report that breastfeeding is linked to lower maternal breast cancer risk, though some findings are limited to premenopausal women or are hedged.
