Coincedence you close comment after Dylan's rebuttal? I doubt it.
Planned Parenthood claims that the National Cancer Institute officially denied abortion as a risk factor for breast cancer in their 2003 conference. But what PP conveniently neglects to mention is that the decision to do so was purely political and was accompanied by many dissenting voices, like Joel Brind of Baruch College. Brind, a Ph.D. endocrinologist in New York City, complains that the conference "refused to allow attending scientists to present the opposing position of the scientific research establishing the link, showing that abortion was declassified as a cancer risk for political and not scientific reasons." They also ignore the inconvenient fact that the NCI's lead researcher has now completely retreated from her position.

Darrell Birkey, the research director for American Right to Life, confirms, "Louise A. Brinton was largely responsible for getting the government-funded NCI to deny the abortion-breast cancer link ... she has now reversed herself and co-authored a study which includes 'induced abortion' as a significant breast cancer risk factor."
