The Abortion -Breast Cancer Link

Breast cancer in America has increased by 50% since abortion was legalized in 1973. Twenty-four published studies worldwide show a link between abortion and breast cancer, particularly the abortion of a first pregnancy. Don’t just take our word for it.

The single most avoidable
risk factor
for breast cancer is...

...elective abortion.

13 out of 14 studies since 1957-show more breast cancer among American women who chose abortion (27 of 33 studies worldwide).

The only study of American women which relied entirely of medical records of abortion (not interviews after the fact) reported a 90% increased risk of breast cancer among women who had chosen abortion.

Even Planned Parenthood's own expert admits that a young woman who aborts her first pregnancy is more likely to get breast cancer later on, than a young woman who carries her first pregnancy to term.

ABC Link - The Abortion- Breast Cancer Link: What Every Woman has the Right to Know

Britta Stream, Miss Oregon of the 2002 Miss America pageant introduces three young women whose lives were forever changed after they developed breast cancer following their abortions. You will hear their stories along with convincing scientific evidence presented by two world experts on the Abortion-Breast Cancer Link, Dr. Joel Brind, PhD, Professor of Human Biology and Endocrinology, and Dr. Angela Lanfranchi MD, FACS, Clinical Assistant Professor of Surgery at Robert Wood Johnson Medical School. The information on this special will empower women to make informed choices for themselves and their children. Women who are at increased risk for breast cancer after an abortion will learn about life saving screening mammograms which can increase survival if breast cancer should develop.

Breast Cancer Abortion Link Fact Sheets

The Breast Cancer Prevention Institute provides 6 fact sheets regarding the Abortion Breast Cancer (ABC) link and the studies aimed at refuting this link. These documents show the definitive facts linking breast cancer to induced abortion and reveal the truth behind the studies that deny it.

FACT SHEET 1: Reproductive Breast Cancer Risks and Breast Lobule Maturation
February, 2007

Ultimately, the majority of breast cancer cases is the result of mutation in the course of cell division (in mitosis, there is a chance that a flawed cell may form; a cancer cell may result when a flawed cell produces an even further flawed cell). High levels of estrogen accelerate this mitosis of breast cells. Pregnancy is an instance where estrogen levels would be elevated as such. However, through the course of a full-term pregnancy, the breast lobules mature to a state in which they become cancer resistant. In the case where an abortion is induced, not only do the breast lobules not fully mature, but they also greatly increase in quantity; this proliferation of immature lobules increase the odds of cancer developing, simply as a result of possessing more places where the cancer may originate.

FACT SHEET 2: Abortion and Breast Cancer: re: "collaborative reanalysis of data" published in Lancet

The most noteworthy study that aimed at denying the ABC link was one conducted by Valerie Beral. The Beral study was a reanalysis of data from 53 epidemiological studies. Beral concluded that there was no link between breast cancer and abortion. Beral’s study, however, was greatly skewed in favor of induced abortion. Omitted from the material on which the study was based, were several valid studies which showed a clear correlation between breast cancer and induced abortion; included into the material, were several studies, proven to be flawed, which showed no correlation. Reasons given for omitting the valid studies were unscientific and highly inappropriate.

In order to mislead the reader, the Beral study compares the risk of breast cancer between a woman who had an induced abortion with one who never become pregnant (to conclude that there is no difference). The more appropriate comparison would be between a woman who had an induced abortion with one who carried the pregnancy to term (which would reveal a much greater risk of cancer in having the abortion). Incidentally, a Beral study testing the risk of breast cancer from hormone replacement treatment (HRT) compared postmenopausal women taking HRT to postmenopausal women without HRT rather than to premenopausal women (to parallel the comparison of post-abortive women with women who never became pregnant). This inconsistency is just one example of how Beral has unprofessionally conducted this study.

FACT SHEET 3: Re: Review of Abortion-Breast Cancer link (ABC link) at National Cancer Institute (NCI) workshop on "Early Reproductive Events and Breast Cancer Risk", held Feb 24-26, 2003

Simply put, the National Cancer Institute workshop that reviewed the ABC link was a farce. Though claiming impartiality, the organizers made every possible attempt to squash the validity of the link between induced abortion and breast cancer, prior to the workshop even beginning. The following are examples indicating such: The scientist invited to make the formal ABC link presentation had not even published in the same field of expertise (expert in breast cancer in relation to obesity and exercise). New data “proving” no ABC link were presented, yet no attempts to question the data were allowed. The conference ended abruptly thereby denying any expression of dissent. No minority or dissenting report was solicited. The end result was that the approval of findings by NCI Boards of Scientific Advisors and Scientific Counselors was considered "unanimous".

FACT SHEET 4: The Biologic Cause of the Abortion Breast Cancer Link: The Physiology of the Breast
May, 2003

There are two factors that influence the possibility of breast cancer: estrogen exposure and breast lobule maturation. The more estrogen to which one has been exposed the greater the risk of breast cancer. Estrogen promotes the growth of breast lobules and every breast cell produced has a chance of being abnormal which has the chance of producing a cell that is cancerous. The longer one is exposed to estrogen, the more opportunities arise for cancer to form, the higher the chances of breast cancer become. The earlier a woman’s breast lobules mature the lower the risk of breast cancer. Mature breast lobules unlike immature lobules are cancer resistant. The only means of developing mature lobules is to give birth. The earlier one gives birth, the quicker one’s lobules fully mature, the lower the chances of breast cancer become. The greatest risk of breast cancer occurs in one who has undergone an induced abortion. In this case, there are an increased number of immature lobules (the abortion occurs after the lobules increase greatly, but before they mature fully). The larger the number of immature lobules, the greater the instances of potential cancer, considering all things, the much higher the chances of breast cancer become.

FACT SHEET 5: Recall Bias: An Argument Used Against the Abortion Breast Cancer Link
May, 2003

The most known and widely spread argument used to counter the ABC link is the theory of recall bias. Recall bias is a phenomenon in which victims of breast cancer are said to be more willing to admit a past abortion than those who do not suffer from breast cancer are. The reasoning behind this theory is that women who suffer from breast cancer desperately seek an explanation for their condition and are willing to disclose information on past abortions to satisfy that need. Women who do not suffer from breast cancer have different priorities. They are more influenced by the embarrassment of having an abortion and therefore are more likely to conceal that information. This bias results in a correlation perceived as an ABC link. Incidentally, recall bias is accepted as tainting only studies involving the ABC link. Logically, recall bias should influence all studies involving unacceptable behavior. However, in studies aimed at linking alcohol consumption to liver damage and number of sexual partners to cervical cancer, researchers do not consider the influence of recall bias. So women who do not suffer from breast cancer are too embarrassed to admit an abortion, yet those who do not suffer from liver damage will freely admit heavy drinking and those who do not have cervical cancer will openly announce their being promiscuous. It seems the concept of recall bias is itself a form of bias.

FACT SHEET 6: Early Reproductive Events and Breast Cancer: A Minority Report
March 10, 2003

On February 26, the NCI workshop concluded with a unanimous agreement against the existence of the ABC link. However, Dr. Joel Brind was a participant of the workshop who did not quite agree with its findings. Though officially there is no mention of any form of dissent in regard to the workshop, Dr. Brind had, in fact, made his dissent. In his formal dissent, Dr. Brind emphasized the one-sided nature of the event. All presentations pushed the notion of no ABC link, and no one in favor of the ABC link was permitted to make any presentation or even discuss the issue. New data against the ABC link was presented, but not allowed to be examined or scrutinized as the data would not be revealed until publication (It would have been appropriate for information to be revealed prior to the workshop so that discussion and review could be made). And despite the workshop’s predetermined finding "Induced abortion is not associated with an increase in breast cancer risk,” Dr. Brind maintained his conviction that there is an ABC link, based off of the findings of various studies. The facts support the ABC link and are open to scrutiny unlike the findings of the NCI workshop.

Its Link to Abortion and the Birth Control Pill
Chris Kahlenborn, MD

"Breast Cancer: Its Link to Abortion and the Birth Control Pill provides a wealth of research information on how induced abortion and the use of oral contraceptive pills influence the risk of developing breast cancer. Dr. Kahlenborn does an excellent job of clarifying the issues in this complex and frequently controversial research area that is of vital importance for the health and well being of women."
