"LONDON (Reuters) - British scientists confirmed on Friday what researchers have long suspected--breast-feeding reduces a woman's risk of developing breast cancer ( news - web sites). Along with having several children, breast-feeding is a key factor in the discrepancy between low rates of breast cancer in developing countries and the rising number of cases in wealthier nations. "The longer women breast-feed, the greater protection against breast cancer," Professor Valerie Beral, of the charity Cancer Research UK, told a news conference.

Beral and her team estimate that if women breast-feed each of their children for an additional 6 months they could cut their life-time risk of developing breast cancer from 6.3% to 6% and prevent more than 1,000 cases of the disease each year in Britain alone. "What we have shown is that prolonging breast-feeding and having more children pushes down breast cancer rates."
