Deniers of the Link Between Abortion and Breast Cancer Ignore the Wave of New Evidence from South Asia



By Joel Brind, Ph.D.

Naomi Elster, described as a scientist and a volunteer for the Abortion Rights Campaign, says, “It’s time to talk about the pseudoscience corrupting the abortion debate.” (The ARC is an Irish coalition organized to make abortion legal on demand in Ireland.)

I couldn’t agree more.  The real question is, of course, who’s peddling the pseudoscience?

Elster certainly claims that major authorities—specifically naming the WHO—are on her side, i.e., “that having an abortion does not increase breast cancer risk.” Plus, she cites her own “background in breast cancer research.”

So for those who have a genuine interest in getting beyond the perennial credentials battle to actually know the truth, I guess I’ll just have to double down on appealing to common sense, including the common sense of biology.

To be clear the only actual scientific evidence Elster cites is “a huge analysis of more than 50 separate research studies with a total of 83,000 breast cancer patients and survivors” (that) found “no evidence” of an abortion-breast cancer link.

I could go on at considerable length to critique this fatally flawed “collaborative reanalysis” by Valerie Beral et al. (as I have done many times before, including in NRL News Today). But when most people see or hear that it was done by researchers at Oxford University and published in the Lancet (one of the premier medical journals in the world), they stop reading or listening (or thinking). It MUST be true.

So I’ll just stick to facts that are absolutely not in dispute and challenge the reader to use common sense and reason.
To begin with, this study Elster cites was published in 2004–13 years ago! Time has not stood still. Millions of abortions have been performed since that time (as well as decades before), and millions of cases of breast cancer cases have been diagnosed worldwide since then as well.
Therefore I must ask if those on my side, who insist that there is a link between having an induced abortion and increasing the risk of having breast cancer–the ABC link–should we then not be witnessing a worldwide explosion in breast cancer incidence since 2004? 
Would this not be especially evident in places where abortion has skyrocketed, such as China and South Asia over the last few decades? (Remember breast cancer often takes 20 years to show up following an event that may trigger it, such as abortion.)

What Role Might Bias Play in the Abortion/Breast Cancer Link Controversy?


By Wendy Smith
Live Action News


There is contradictory scientific evidence regarding a link between abortions and breast cancer. Could this research be biased one way or another? Can we rely on these reports? These are important questions to consider in light of the controversy surrounding abortion and health risks, especially breast cancer.

Dr. Angela Lanfranchi, a practicing breast surgeon and co-founder of the Breast Cancer Prevention Institute (BCPI), feels the link between cancer and either induced abortion and/or the use of hormonal contraception is strong. 


In fact, she has risked her reputation supporting this view since launching BCPI in 1999. Dr. Lanfranchi argues that the biology behind induced abortion and increased risk of breast cancer is solid science, based on exposure to estrogen and rapid breast lobule formation prior to 32 weeks gestation.

Serum estrogen exposure has been identified as a quantifiable risk factor for developing breast cancer, as noted in studies of women who used hormone replacement therapy for longer than 10 years. 

Dr. Lanfranchi makes the point that hormonal contraceptives are class 1 carcinogens and that studies have shown an increase in breast cancer for premenopausal women who took hormonal contraception prior to their first full term pregnancy.

Following conception, in a viable pregnancy, estrogen levels increase 2,000% by the end of the first trimester. During this same time period, there is rapid breast tissue growth as estrogen stimulates breast cell division. Due to this rapid cell division in the setting of high estrogen levels, errors in DNA replication can occur, setting the stage for subsequent breast cancer if the pregnancy is terminated early by an induced abortion (this does not apply in the setting of spontaneous miscarriage).

Dr Lanfranchi and her colleague at BCPI, Dr. Joel Brind, a biochemist, have reviewed countless research reports investigating the possible link between induced abortion and breast cancer. Lanfranchi states:

"Since 1957 there have been 67 studies done concerning induced abortion and breast cancer risk. Of these, 51 showed a positive association and 30 were statistically significant."
