Breast Cancer Link


A newly-published study shows the highest-ever abortion-breast cancer risk for women of any previously-published study on the link between the two.

A Bangladesh study published in the Journal of Dhaka Medical College on risk factors for breast cancer, led by Dr. Suraiya Jabeen, found a statistically significant 20.62-fold increased risk among women with abortion histories. The new study on the abortion-breast cancer link is by far the highest risk elevation reported among 73 published abortion-breast cancer studies.

Observing that women in Bangladesh have very traditional childbearing patterns that reduce breast cancer risk, he explained: “Almost all the women are married (97% currently married; the rest widowed) and with child by the time they are 20, and all of the kids are breastfed. Ninety percent had their first child at age 21 or younger (99% of controls did). They typically neither take contraceptive steroids nor have any abortions. Nulliparity (childlessness) or abortion before first full term pregnancy (both of which mean no breastfeeding) in a population in which breast cancer is almost unheard of, makes the relative risk very high.”

Brind continued: “Although the authors did not include a measure of their abortion link’s statistical significance, their raw data was complete enough to calculate a 95% confidence interval of 12.85-32.51, making abortion by far the strongest and most significant risk factor observed in these Bengali women. In plain English, women in this population who had any induced abortions were more than 20 times as likely to get breast cancer, compared to women with no abortions.”


A study published in the Indian Journal of Community Medicine (May, 2013) found a 6.38-fold greater risk of breast cancer among Indian women with histories of induced abortion.

Study leader Ramchandra Kamath of the Department of Public Health, Manipal University, observed that India has the “largest estimated number of breast cancer deaths worldwide,” and that breast cancer ranks second only to cervical cancer as the most common diagnosed malignancy among Indian women.

Although the study cohort included only 188 participants (94 cases and 94 controls), which the researchers acknowledged limited the “generalisability of the findings,” U.S. expert Dr. Joel Brind said the small study does strongly reconfirm that higher rates of abortion lead to increased risk of breast cancer.

“With only 94 cases and 94 controls, the study was way too small for a significant risk of the order of 1.5-fold to even show up,” said Professor Brind in a statement to the Coalition on Abortion/Breast Cancer. “Yet induced abortion did show up as the strongest risk factor (and right on the border of statistical significance) because the risk increase was so high at 6.38-fold.”


Since 1957 there has been 66 studies done which looked at the relation of induced abortion and breast cancer, including 53 which showed a positive correlation and 25 that were statistically significant. There were only 13 which showed no association.

What is most telling is that one study author, Louise Brinton, had been a leader at the 2003 NCI Workshop on Early Reproductive Events and Breast Cancer Risk which concluded that there was no association between breast cancer and induced abortion. In 2009, Louise Brinton has now reported that there is a 40% statistically significant increase of breast cancer with induced abortion. Recent studies from Turkey, Iran and China have been published in the last 5 years. The list of these studies will be available soon on the BCPI website’s Resources Page. We hope that this list of studies will be useful to you so that women will be informed of this preventable risk.


Many have ignored the mounting evidence for the relationship between abortion and breast cancer (the “ABC” link). This is truly unfortunate, since we believe that women have the right to know all of the facts surrounding abortion. It is highly immoral to withhold any information whatsoever on the topic, especially information of this magnitude. 

It has been discovered that 28 out of 37 worldwide studies have determined that there is, in fact, a link between abortion and breast cancer. Furthermore, 13 out of 15 studies in the United States have also found the ABC link. 

These are not simple statistical anomalies; there is biological reasoning behind the ABC link. When a woman conceives a child, her estrogen level rises over one hundred times. This hormone surge produces undifferentiated cells in a woman’s breasts, which are not differentiated until later on in the pregnancy in order to produce milk for the child. Undifferentiated cells are susceptible to carcinogens that can generate cancerous tumors.

The circle of influence of pro-choice supporters is great, and one might expect that many will ignore and withhold the information. However, this information could mean the difference between life and death for some women. The central focus of the right-to-life movement is life, and this focus includes the lives of all of the precious mothers who deserve to know the facts.


Women contemplating this procedure should consider another risk of abortion: Pelvic Inflammatory Disease (PID). PID is a well-known infection occurring in 5.2% of first trimester abortions and 18.5% of mid-trimester abortions at John Hopkins University. These percentages likely double at some unaffiliated clinic facilities throughout the United States. PID often renders its victims infertile, even with prompt treatment. (M. Spence, “PID Detection and Treatment,” Sexually Transmitted Disease Bulletin JHU, Vol. 3, No. 1, Feb. 83.) 

In addition to the foregoing risks, 1% of women having an abortion will need a blood transfusion, of which 10% will contract Viral Hepatitis. Approximately 2% of these women will die. With 1,600,000 estimated abortions annually in the U.S., that means 32 women a year will die from transfusions needed after having an abortion.


For years abortion advocates and researchers have been asserting that an abortion is in fact safer than carrying a pregnancy to term.  They contend that pregnancy is a long process and the chance of complications during the gestational period and birth is significantly higher than complications resulting from the abortion procedure.

However, a study released this past week demonstrates that this claim is not entirely valid.  New research, which takes into account the full reproductive histories of the women involved, illustrates that, compared to women who delivered their babies, women who had an early- or late-term abortion have significantly higher mortality rates within one to ten years of the event.

In contrast with a 2012 study conducted by researchers from Gynuity Health Projects and the University of North Carolina – which asserts that women are 14 times more likely to die delivering a live baby than from complications of an abortion, this study, which links up all relevant reproductive health data, found that death rates associated with birth were lower than those associated with early-term abortion, late-term abortion, and miscarriage in every year over a 10-year period.

The data demonstrates that an abortion prior to 12 weeks is associated with 80% higher risk of death within the first year after the procedure and a 40% higher risk of death over 10 years.

In light of these findings (and the recent tragic case of 29-year-old Jennifer McKenna Morbelli, who died as a result of an abortion performed on her 33-week-old unborn daughter), it certainly seems advisable that women considering abortion be in full possession of all the facts before they make a choice which could result in consequences far more dire than those they had anticipated.  Improved abortion reporting laws in the United States with record linkages to allow studies similar to this new analysis of Denmark’s data are also urgently needed.


A new study published in the Journal of the American Medical Association finds researchers noting an increase in advanced cases of breast cancer over the last 33 years. However, the authors essentially ignore how abortion plays a great role in that increase.

The authors, led by Rebecca Johnson, MD, reported that the incidence of advanced breast cancer which, by the time of diagnosis, had already spread to distant locations (i.el bone, brain, lungs, etc.) among women aged 25-39 years, had jumped by nearly 90% during a 33 year period.

The rate of advanced breast cancer doubled for African Americans, ages 25-39, climbing from 3.14 in 1976 to 6.25 per 100,000 in 2009, with a statistically significant annual percent change of 3.50, the study indicated. At the same time, black women have abortions at much higher rates than their white counterparts.
