For what it's worth, I recall that Dr. Donohue (you know, the newspaper column guys who's usually next to Dear Abby) shocked me by coming right out and saying breastfeeding reduces your risk of breast cancer! I had never read that before in a mainstream source (though of course I was familiar with it from MDC and similar...)
DEAR DR. DONOHUE: Does breastfeeding protect against breast cancer or make it more likely? I have heard both sides. -- C.N.
ANSWER: Many studies have shown conclusively that breastfeeding lowers the risk for breast cancer. For every 12 months a woman has breastfed, her chances of breast cancer drop by 4.3 percent.
One explanation is that breastfeeding delays ovulation and the production of estrogen.

I know it's not a pamphlet, but it could be quoted in a pamphlet that you made.
