ACOG committee opinion. Induced abortion and breast cancer risk. Number 285, August 2003.
The purpose of this Committee Opinion is to provide a review of recent studies regarding the potential relationship between induced abortion and subsequent breast cancer and to discuss methodologic challenges in this field of study. The American College of Obstetricians and Gynecologists' Committee on Gynecologic Practice concludes that early studies of the relationship between prior induced abortion and breast cancer risk have been inconsistent and are difficult to interpret because of methodologic considerations. More rigorous recent studies argue against a causal relationship between induced abortion and a subsequent increase in breast cancer risk.
