Its components are easy to digest and include antibodies that can protect infants from bacterial and viral infections and growth factors that may prevent chronic diseases later in life. Research indicates that women who breastfeed may have lower rates of certain breast and ovarian cancers and are more likely to return to their pregravid weight faster than those who do not breastfeed.
