Women still confused by the breast milk vs. formula debate may want to listen up, as a new study has found exclusively breastfeeding your baby for at least six months could cut your chances of dying from cancer and all other diseases by 17 percent—and death by heart disease alone by 8 percent. 

The mass study, published online Wednesday in the American Journal of Clinical Nutrition, examined breastfeeding and other lifestyle recommendations from the American Institute for Cancer Research (AICR) and its umbrella World Cancer Research Fund International and their effects on nearly 380,000 people in several European countries over 13 years.
