In brief: Theoretical
No one knows for sure.
One theory is that breast feeding makes the cells in the breast do what they are meant to do-- make breast milk. Cancers often arise from cells in our body that haven't matured fully. The hormones your body produces when breast feeding force breast cells to "grow up", making them less likely to become a cancer later on.
