Breastfeeding may reduce your risk of some types of cancer
Numerous studies have found that the longer women breastfeed, the more they're protected against breast and ovarian cancer. For breast cancer, nursing for at least a year appears to have the most protective effect. It's not entirely clear how breastfeeding helps, but structural changes in breast tissue caused by breastfeeding and the fact that lactation suppresses the amount of estrogen your body produces may play roles. Researchers think the effect on ovarian cancer may be related to estrogen suppression as well.
