Breastfeeding for 6 Months Cuts Women’s Risk of Cancer Death: Study
Mothers who breastfeed for at least six months have a 10 percent lower risk of dying from cancer and a 17 percent lower risk of dying from circulatory disease, according to a new study.
Researchers examined the habits of nearly 380,000 people in nine European countries and found that those who followed World Cancer Research Fund advice on cancer-prevention lifestyles had about a one-third lower risk of death from several major diseases, The Telegraph in the U.K. reported.
