Until quite recently we were still more or less agnostic on the purported abortion/breast cancer link, but study after study, from all over the world, seem to indicate that there is indeed such a link. Today, Steve Ertelt, writing at LifeNews brings news of ANOTHER study by reputable scientists asserting a link between breast cancer and induced abortions.
"A new study published in the Asian Pacific Journal of Cancer Prevention in February reported a very statistically significant increased risk of breast cancer for women with previous abortions as opposed to women who have never had one.
The study, consisting of 1,351 women and led by researcher Ai-Ren Jiang, reported a statistically significant 1.52-fold elevation in risk for women with induced abortions and a “significant dose-response relationship between (the risk) for breast cancer and number of induced abortions,” meaning the risk climbed with a higher number of previous abortions."
In 2010, we reported on four recent independent studies in Turkey, China, Sri Lanka, and Seattle. All four concluded that there is indeed an increased risk for breast cancer in post-abortive women. All four studies were published in significant professional medical journals. We re-post the part of our article describing the four studies:
"The Chinese study “A case-control study of reproductive factors associated with subtypes of breast cancer in Northeast China,” was published in the Journal of Medical Oncology on September 23, 2009. The study’s abstract concluded: “Breastfeeding protected parous women from any subtype of breast cancer. Postmenopause and spontaneous abortion were inversely associated with the risk of luminal tumors. By contrast, multiparity, family history of breast cancer and induced abortion increased the risk of breast cancer.”
The Turkish study “Breast cancer risk factors in Turkish women – a University Hospital based nested case control study” was published on April 8, 2009 in the World Journal of Surgical Oncology. It concluded: “These findings suggest that age and induced abortion were found to be significantly associated with increased breast cancer risk whereas oral contraceptive use was observed to be associated with decreased breast cancer risk among Turkish women in Istanbul.”
The Sri Lankan study “Prolonged breastfeeding reduces risk of breast cancer in Sri Lankan women: a case-control study” was published in Cancer Epidemiology in June 2010. It concluded, in part: “The significant factors associated with increased risk of breast cancer were: post-menopausal women (OR=1.74; 95%CI=1.01, 3.01); having an abortion in the past (OR=3.42; 95%CI=1.75, 6.66) and exposure to passive smoking (OR=2.96, 95%CI=1.53, 5.75).”In other words, as the Daily Mail UK reported, although the study was focused on the association between the duration of breastfeeding and the risk of breast cancer, other risk factors were discovered, and “the highest of the reported risk factors was abortion.”
The Seattle study “Risk Factors for Triple-Negative Breast Cancer in Women Under Age 45” was published in April 2009 in Cancer Epidemiology Biomarkers and Prevention. The study concluded, in part: “In analyses of all 897 breast cancer cases (subtypes combined), the multivariate-adjusted odds ratios for examined risk factors were consistent with the effects observed in prior studies of younger women . Specifically, older age, family history of breast cancer, earlier menarche age, induced abortion, and OC (oral contraceptive) use were associated with an increased risk of breast cancer.”
The Seattle study was remarkable not just for its conclusion, but because of the identity of one of the authors, Dr. Louise A. Brinton, MPH, Ph. D. It so happens that Dr. Brinton works for the National Cancer Institute and was one of the organizers of the NCI’s 2003 workshop that produced the study that NARAL cites as the sole authority for their sweeping claim of no abortion/breast cancer link. Unfortunately for NARAL, while Dr. Brinton may have held that opinion in 2003, she no longer does. From the Daily Mail UK 'Earlier this year, Dr Louise Brinton, a senior researcher with the U.S. National Cancer Institute who did not accept the link, reversed her position to say she was now convinced abortion increased the risk of breast cancer by about 40 per cent.'”
