According to data from 44,000 women who participated in the studies analyzed, researchers found no increase in breast cancer risk among women who had a pregnancy that ended in miscarriage or abortion. In fact,
women who had a pregnancy that ended in abortion had a slightly lower (7%) risk of breast cancer, and the number of abortions was not associated with any change in breast cancer risk.
Damn, it's actually the opposite!
Bsically they find a woman who has breast cancer, ask her if she had an abortion, and if she said 'yes', they say she got cancer because of the abortion. It's like asking someone who got into a car wreck if they had cheese the night before.
"OMG cheese causes car crashes!".
I personally don't see how an abortion can cause any form of cancer. If it were true, a tongue scraping would cause cancer of the tongue or the foot
