An April 2009 study co-authored by a researcher who has previously denied an abortion-breast cancer link shows a statistically significant increase in breast cancer risk among women who have had abortions or who use oral contraceptives. The study by researchers including Jessica Dolle of the Fred Hutchinson Cancer Research contained a table reporting a statistically significant 40 percent risk increase for women who have had abortions. According to the Coalition on Abortion/Breast Cancer (CABC), the study listed abortion as among “known and suspected risk factors.”
The CABC says that one co-author of the study, U.S. National Cancer Institute (NCI) researcher Dr. Louise Brinton, had organized a 2003 NCI workshop on the abortion-breast cancer link. That workshop reportedly said the non-existence of an abortion-breast cancer link was “well established.”
CNA contacted Dr. Brinton for comment but did not receive a reply by publication time.
Dr. Joel Brind, who is a CBCP advisor and president of the Breast Cancer Prevention Institute and a professor of endocrinology at Baruch College at City University of New York, said that the study’s findings on abortion were not new.
Rather, they repeated the “modest but significant” findings of the 1990s which found a breast cancer risk factor increase of between 20 and 50 percent.
