A member asked:

How does breast feeding lower the risk of breast cancer?

A doctor has provided 1 answer

Several theories.: We don't currently know "exactly" how. Breast feeding for six months and longer seems to make a difference. One theory is that milk production keeps the cells busy so that they don't have the energy to mutate into cancer. Another is that toxins are drained with milk production. Another is that hormone levels with milk production are protective - estrogen, progesterone, prolactin, oxytocin etc.
