An article in The Guardian cites a recently concluded Spanish study determined that cancer rates could be cut if many more women breastfed.
Based on these findings, the incidence of this disease could be reduced from 6.3% to 2.7% if women breastfed their children for more than six months," the authors say. A move away from breastfeeding is a crucial factor behind an increase in breast cancer cases, they add.
The findings confirm the results of other studies. Both breastfeeding and pregnancy are thought to help protect women against breast cancer by reducing oestregen levels.
