According to LifeSiteNews.com, researches have conducted a review of 72 studies. The study, “Breast Cancer and Induced Abortion: A Comprehensive Review of Breast Development and Pathophysiology, the Epidemiologic Literature, and Proposal for Creation of Databanks to Elucidate All Breast Cancer Risk Factors,” by Dr. Angela Lanfranchi and Patrick Fagan, Ph.D., was published in Issues in Law and Medicine. Their conclusion was that there is enough evidence of a link between abortion and breast cancer that a systematic, robust study of the link is warranted. The mechanism involved appears to be the same mechanism that causes an increase in breast cancer for those who are childlessness, have premature birth before 32 weeks, and have second trimester miscarriages.
The authors analyzed the 72 epidemiological studies using guidelines that establish nine criteria that help determine whether a cause-effect relationship exists between a potential risk factor and a disease.
After demonstrating that all nine criteria were met in the epidemiological evidence, Lanfranchi and Fagan stated: “We see that many studies of induced abortion demonstrate significant associations, across multiple cultures and with some apparent specificity of cause, such as hormone exposure. The association manifests itself in the appropriate order, demonstrates a dose effect, is biologically plausible and coherent with existing science and has been demonstrated by analogy.”
