Does Abortion Cause Breast Cancer ?

Yes, it does.

What Causes Breast Cancer ?

What Are Risk Factors For Breast Cancer ?

On October 15, 2010, The Centers for Disease Control and Prevention (CDC) announced it had invited 15 individuals to serve on the Advisory Committee on Breast Cancer in Young Women, a federal advisory committee established by the Affordable Care Act. The Affordable Care Act charges CDC with the responsibility of developing initiatives to increase knowledge of breast health and breast cancer among women, particularly among those under the age of 40 and those at heightened risk for developing the disease.

Now here's something for you to chew on...

There are five breast cancer research papers published very recently in year 2009 - 2010 which state in their findings that induced abortion is linked to elevated breast cancer risk. This blog focuses on the 7 most recent studies from 2009 - 2011 although in the past 5 decades, there have been approximately 50 studies linking abortion to breast cancer. Here is a list of epidemiologic studies investigating induced abortion and breast cancer risk: http://www.bcpinstitute.org/epidemiology_studies_bcpi.htm

Unfortunately, the "Advisory Committee on Breast Cancer in Young Women" consisting of external experts, who are suppose to assist CDC in increasing public understanding & awareness of breast cancer among young women, is under tremendous political pressure by pro-choice politicians to conceal the two largest risk factors for breast cancer in women under age 45: oral contraceptives & abortion. It has been estimated that 42% of women in the U.S. have had an abortion by age 45 and this has contributed to the increase in breast cancer in women under age 45 along with the popularity of the birth control pill. Incidentally, Dr. Thomas Frieden, Director of Centers for Disease Control & Prevention served as health advisor to New York City Mayor Michael Bloomberg - an enormous abortion enthusiast who mandated abortion training for all OBGYN resident doctors in New York. Dr. Frieden was appointed to his position as Director of Centers for Disease Control & Prevention by Obama who ardently favors taxpayer funded abortion.

Despite 5 new breast cancer research studies linking induced abortion to elevated breast cancer risk, the federally funded U.S. National Cancer Institute (NCI) has been slow to include this information on their website & only mentions discussions from a 7 year old NCI breast cancer workshop from 2003. U.S. National Cancer Institute is reluctant to include the new findings on their website due to political pressures by pro-choice politicians who fear the wide public broadcast of the new findings in the media will affect the legality of abortion. American Cancer Society was also pressured to remove induced abortion as a breast cancer risk factor from their website & their current website completely lacks information & even acknowledgment of the new year 2009 to 2010 breast cancer research linking abortion to breast cancer. Centers for Disease Control & Prevention's "breast cancer prevention research & awareness activities for the public" is more of a smoke screen. Dr. Thomas Frieden is likely more interested in suppressing abortion-breast-cancer research than "creating awareness that abortion is linked to elevated breast cancer risk." Interestingly, some of the 15 individuals to serve on his new Advisory Committee have also been accused of being associated with groups trying to suppress abortion-breast-cancer links. The true motive of the new Advisory Committee on Breast Cancer in Young Women recently created by the CDC is questionable.

(As a side note, it is interesting to mention that it took several decades for the National Cancer Institute - NCI to openly admit the link between smoking & lung cancer. Research emerged in the early 1900's that smoking was associated with elevated lung cancer risk. After the National Cancer Institute was founded in 1937, big tobacco companies started to donate "research grants" to the NCI to "further study the matter" as they feared the unfavorable research would adversely impact profits. Unsurprisingly, NCI started churning out denials of the smoking-lung-cancer link until the evidence became overwhelming irrefutable & due to litigation. According to Former Food and Drug Administration Chairman Dr. David Kessler's book, "A Question of Intent," tobacco money corrupted the American Medical Association, leading medical research facilities (Harvard, UCLA, Sloan Kettering, etc...) and esteemed scientists and physicians (eg: Clarence "Pete" Little who was a leader of the National Cancer Institute and the American Cancer Society). Many people draw parallels to the abortion-breast-cancer link as the $1 billion a year U.S. abortion industry continually donates to U.S. politicians. Even Obama's Health Secretary, Kathleen Sebelius, has openly admitted to receiving campaign donations from the abortion industry.

1st Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:

Fred Hutchinson Cancer Research & National Cancer Institute stated abortion is linked to elevated breast cancer risk in a 2009 published research paper titled, "Risk Factors For Triple-Negative Breast Cancer In Women Under The Age of 45 Years." Study was published in Cancer Epidemiol Biomarkers Prevention Journal 2009: 18 (4) April 2009.

Line 3-5 at the top left column of page 1163 in Cancer Epidemiol Biomarkers Prevention Journal, the study clearly concludes, ".....induced abortion & contraceptive use were associated with increased risk for breast cancer."

The last row of Table 1 on page 1158 also states a single abortion raises breast cancer risk by 40%

In this paper, the authors list in Table 4: Multivariate adjusted case-control odds ratios for all breast cancer cases, triple-negative and non-triple-negative cases, in relation to oral contraceptive risk factors, stratified by age at diagnosis under age 40 and 41-45 y, the following devastating information:

The risks for acquiring the deadliest, most aggressive and difficult to treat form of breast cancer, Triple Negative Breast Cancer based on age of first use of oral contraceptives is:

Age 22+: 250%
Age 18-22: 270%
Age Under 18: 540%

In other words, this research paper indicates that women who begin oral contraceptive use before age 18 are at a 540% increased risk of developing the most aggressive and deadly form of breast cancer, triple negative breast cancer.

2nd Breast Cancer Research Paper (1996) Linking Abortion To Breast Cancer:

This study was conducted by Fred Hutchinson Cancer Research & was published in American Journal of Epidemiology. It concludes in part, “Among women who had been pregnant at least once, the risk of breast cancer in those with a prior induced abortion was 20% higher than that in women with no history of abortion (95% confidence interval 1.0–1.5). “

To read: http://aje.oxfordjournals.org/content/144/4/373.short

"Among women who had ever been pregnant, the breast cancer risk in those with one or more induced abortion was 1.2 (95% confidence interval [CI], 1.0-1.5) relative to women with no abortion history. The breast cancer risk was greatest (2.0; 95% CI, 1.2-3.3) among nulliparous women whose abortion or abortions occurred prior to 8 weeks' gestation. This risk was slightly higher when the abortion was performed before 20 years of age (1.5) or after 29 years of age (1.4)."

3rd Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:

This study was published in reputable Journal of Surgery Oncology 2009:

Turkish breast cancer study. Citation: Ozmen et al. Breast cancer risk factors in Turkish women - a university hospital-based nested case control study. Published in World Journal of Surgery Oncology 2009;7:37 Turkish study reported a statistically significant 66% increased risk of breast cancer for women with abortions. 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.

4th Breast Cancer Research Paper (Year 2009) Linking Abortion To Breast Cancer:

China breast cancer study by Xing P, Li J, Jin F. A case-control study of reproductive factors associated with subtypes of breast cancer in Northeast China.” Humana Press, e-publication online September 2009. The study’s abstract concluded: “Breastfeeding protected parous women from any subtype of breast cancer. Postmenopause and spontaneous abortion (ie: miscarriage) 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.”

5th Breast Cancer Research Paper (Year 2010) Linking Abortion To Breast Cancer:

Sri Lanka - De Silva et al. Cancer Epidemiol. 2010 Jun;34(3):267-73. Epub 2010 Mar 24.
Title of research paper, “Prolonged breastfeeding reduces risk of breast cancer in Sri Lankan women: a case-control study.” Published by De Silva M, Senarath U, Gunatilake M, Lokuhetty D

Department of Community Medicine, Faculty of Medicine, University of Colombo, 25 Kynsey Road, Colombo, Sri Lanka.

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.”

6th Breast Cancer Research Paper (Year 2010) Linking Abortion To Breast Cancer:

Researchers in Iran have published the results of a new study showing women who have an abortion face a 193% increased risk of breast cancer. On the other hand, women who carry a pregnancy to term find a lowered breast cancer risk compared with women who have never been pregnant.

Title of breast cancer research paper is, “Reproductive factors associated with breast cancer risk in northern Iran” and the findings were reported in the April 3, 2010 issue of Medical Oncology.

Researchers Hajian-Tilaki K.O. and Kaveh-Ahangar T. from Babol University of Medical Sciences compared 100 cases of women who were newly diagnosed with breast cancer compared with 200 age-matched controls to review several reproductive factors.

The researchers discovered abortion significantly elevated breast cancer risks. Also, having a first pregnancy at an older age increases the breast cancer risk by 310 percent.

The study's abstract concluded in part, “Nulliparity, late age at first birth and abortion were the most important reproductive factors associated with breast cancer risk; therefore, it is recommended to women with these risk factors to perform breast cancer screening tests earlier."

7th Breast Cancer Research Paper (Year 2011) Linking Abortion To Breast Cancer:

A new study published by scientists who examined diabetes mellitus type 2, reproductive factors, and breast cancer found a statistically significant association showing a 2.86-fold increased breast cancer risk from one induced abortion.

The study, led by Lilit Khachatryan, included researchers from Johns Hopkins School of Public Health and the University of Pennsylvania. Khachatryan is from the Department of Public Health, American University of Armenia, Yerevan, Armenia; Robert Scharpfb is from the Johns Hopkins School of Public Health and Sarah Kagan is from the School of Nursing at the University of Pennsylvania.

The study, published in Taylor & Francis, also found that delaying a first full-term pregnancy, which is frequently done by women having abortions, also raises the breast cancer risk wheras giving birth resulted in a 64% reduced risk.

"Each year delay in first pregnancy increased risk (adjusted OR = 1.13, 95% CI 1.01–1.27) as did induced abortions (adjusted OR = 2.86, 95% CI 1.02–8.04)."

Here is the e-mail to a breast cancer surgeon, Dr. Angela Lanfranchi in New Jersey, who supports the abortion-breast-cancer link: info@bcpinstitute.org. Her phone is 1-86-NO CANCER (1-866-622-6237). According to information from Dr. Lanfranchi's website (www.bcpinstitute.org/factshts.htm), the 6 criteria have been met to established that induced abortion is a cause of breast cancer. For more information, visit:

http://www.pinkmoney.org/criteria_causal_a_bc.htm

Dr. Joel Brind, a Yale University graduate who is a professor of biology and endocrinology at Baruch College, also supports abortion-breast-cancer link & he can be reached at Joel_Brind@baruch.cuny.edu.

Dr. Chris Kahlenborn is an American medical doctor, specializing in internal medicine at Altoona Hospital / Bon Secours Hospital in Pennsylvania, U.S.A. He has authored a book on the abortion-breast-cancer link and can be reached at drchrisk@polycarp.org. Dr. Kahlenborn graduated from Penn State Medical University in 1988 and has been doing research on the effects of oral contraceptives on breast cancer for well over ten years. In June 2000 he testified on the topic of breast cancer before the Federal Drug Administration (FDA) in Washington D.C. His most recent publication, published in the Mayo Clinic Proceedings in October, 2006 is called “Oral Contraceptive use as a risk factor for premenopausal breast cancer.” For more info, visit http://www.imfcanada.org/default.aspx?go=article&aid=448&tid=8

Dr. Gerard Nadal also supports the abortion breast cancer link. He holds a Master of Science in Cellular & Molecular Biology & a Master of Philosophy in Biology, and a PhD in Molecular Microbiology from Saint John's University, New York City. Dr. Nadal can be reached at gerardnadal60@gmail.com.

The U.S. National Cancer Institute (NCI) website mentions that it hosted a breast cancer workshop in 2003 to explore the abortion breast cancer issue. It is also mentions that the workshop resulted in a denial of the abortion breast cancer link. Unfortunately, individuals who supported the abortion breast cancer link were either not invited to the workshop or were not allowed to speak if they were in attendance. None of the above mentioned medical doctors, breast surgeon & scientists were invited to attend the workshop except for Dr. Brind & therefore did not have an opportunity to present their support of the abortion breast cancer link. Of the above mentioned individuals, only Dr. Brind was in attendance at this breast cancer workshop but he was not allowed to present his statistical analysis of data to support the abortion breast cancer link. He did manage to file a dissenting opinion at the NCI workshop. Dr. Janet Daling from Fred Hutchinson Cancer Research who has studied the abortion breast cancer link extensively & supports the abortion breast cancer link was in attendance but was instructed to present on an entirely different topic by Dr. Louise Brinton (Chief Hormonal & Reproductive Epidemiologist at the U.S. National Cancer Institute) & was not given the opportunity to present research to support the link. To further read how the National Cancer Institute deliberately orchestrated the breast cancer workshop to suppress the discussion of research linking induced abortion to elevated breast cancer risk, please visit http://www.bcpinstitute.org/abc_nci.htm

In case you want to contact Dr. Brinton to ask her about why the National Cancer Institute has not updated their website to include new breast cancer research linking abortion to breast cancer: brintonl@mail.nih.gov. Specifically, you might want to ask Dr. Louise Brinton why the National Cancer Institute website contains information that is in complete contradiction to her own research (ie: her own research with Dr. Brinton's name & NCI's name on the front page was published in April 2009 clearly stating that abortion is linked to elevated breast cancer risk with a 40% increased risk associated with abortion; however, her organization's website (NCI) completely denies the link exists). Perhaps Dr. Brinton's research paper contained a Freudian slip - an accidental admission of the abortion-breast-cancer link? Hmmm....

You might also like to examine how Dr. Karin Michels, Associate Professor of Obstetrics, Gynecology & Reproductive Biology at Harvard Medical School & Associate Professor, Department of Epidemiology Harvard School of Public Health has been accused of publishing potentially fraudulent breast cancer research that seems to deliberately deny & refute the abortion-breast-cancer link. As seen in the above links to recent 2009-2010 breast cancer research, there is much evidence that refutes the findings in Dr. Karin Michels breast cancer study. Dr. Karin Michels has been accused of publishing potentially fraudulent breast cancer research by attorney Andy Schlafly who is General Counsel for the Association of American Physicians & Surgeons. Dr. Karin Michels has been accused of deliberately manipulating design & methodologies of the study to skew the results.

For example, Dr. Michels included an unusually large number of post-abortive women in their twenties to participate in the study. Due to the long latency of breast cancer, the harmful carcinogenic effects of abortion would not show up until decades later when these women would be in their thirties, forties, fifties etc. Therefore, it appears that abortion has no adverse impact on these post-abortive women in regards to increased breast cancer rates since they were only in their twenties when they participated in the study.

Furthermore, over 28,000 women (approximately 25% of the participants in this study) refused to answer the question asking if they had an induced abortion. Dr. Michels automatically classified these women as never having had an abortion although the more logical conclusion would be that these 28,000 women did not want to admit they had an abortion & should have been classified as having had an abortion. This potentially huge misclassification could easily skew the results to show no correlation between abortion & breast cancer risk.

In addition, on page 815, Dr. Michels deliberately omitted 399 post-abortive women who had recently developed breast cancer from the study. Why did Dr. Michels exclude from her analysis women who had an induced abortion and were newly diagnosed as having breast cancer? This is an illogical exclusion as the main purpose of Dr. Michels' study is to examine if & how abortion adversely impacts women's health. To see more examples of how Dr. Michels manipulated the methodologies & design of her study, please see the links directly below.

Here are links to 2 criticisms of the Dr. Michels Harvard breast cancer study published in 2007 (one of them accuses Dr. Michels of publishing potentially fraudulent research to appease her funding source - U.S. National Cancer Institute):

http://www.conservapedia.com/Harvard_abortion_study

Please also note that scientists studying cancer in U.S.A. depend largely on grants from National Institutes of Health (National Cancer Institute). In a year 2005 study, “Scientist Behaving Badly,” the scientific journal Nature* revealed that in an anonymous questionnaire, 15.5% of scientists admitted to changing design, result, methodologies in response to funding source (B. Martinson et al “Scientists Behaving Badly” Nature 435:9). The 2007 Harvard Abortion Breast Cancer Study minimizing the effect of induced abortion on breast cancer was funded by grant # CA50385 from the National Cancer Institute. The researchers at Harvard were dependent on the National Cancer Institute for funding. In turn, National Cancer Institute depends on the U.S. government for funding. Currently, many elected U.S. politicians have received hefty campaign donations from the political arm of the largest abortion provider Planned Parenthood - Planned Parenthood Action Fund & from EMILY's List which is a openly pro-choice U.S. political action committee whose main purpose is to fund pro-choice U.S. politicians to help them become elected inorder to secure abortion favorable legislation & to impose abortion favorable ideology on government agencies such as the U.S. National Cancer Institute. To see EMILY's List website that openly admits that its goal is to impose pro-abortion ideology on government, visit http://www.emilyslist.org/about/ . Prior to the midterm U.S. elections in 2010, even more abortion-backed politicians held seats in the U.S. Congress although many of these pro-abort Congressmen lost their seats to pro-life politicians backed by the Tea Party.

There is an obvious conflict of interest experienced by the Harvard researchers who published the breast cancer study minimizing the effects of induced abortion on breast cancer. However, scientists studying breast cancer in China, Turkey, Sri Lanka and Iran who do not rely on pro-abortion politicians for funding reported in year 2009 & 2010 that there is indeed significant elevated breast cancer risk in women with abortions.

Harvard Abortion Breast Cancer study was published in Archives of Internal Medicine April 2007;167(8):814-820
Here is a copy of the Harvard abortion-breast-cancer study:

Furthermore, informed consent is a legal obligation requiring physicians to fully inform their patients of the risks associated with any surgical procedures including abortion. Physicians who do not inform their patients of the elevated breast cancer risk associated with abortion expose themselves to considerable legal liability and can be sued for medical malpractice. So far, there are five successful lawsuits involving women who sued their abortion doctors for not informing them that abortion is associated with increased breast cancer risk. Two successful lawsuits are in U.S.A. & three successful lawsuits are in Australia. Here are some examples:

1) Dr Charles Benjamin & Cherry Hill Women's Center in New Jersey paid a settlement to a 19 yr old patient, Stephanie Carter, for failing to disclose abortion-breast-cancer-risk. Dr. Benjamin performed an abortion on Carter when she was 17. Carter's parents claim that her guidance counselor advised her to get an abortion in suburban Cherry Hill, N.J., where state parental notification laws aren't as strict as Pennsylvania's.

Although Carter's abortion was performed in New Jersey, her attorney, Joseph Stanton sued Dr. Benjamin under a Pennsylvania law that says failure to obtain informed consent constitutes battery.

2) All Women's Health Services, abortion clinic in Portland, Oregon, paid a judgment to a female plaintiff for not disclosing abortion-cancer link. Plaintiff's attorney, Jonathan Clark, can be reached at 960 Liberty Street SE, Suite 250, Salem, Oregon 97302. Office tel: (503) 274-1100 at law firm O'Donnell & Clark.

3) Australian attorney Charles Francis won lawsuit on behalf of woman suing abortionist for not disclosing abortion-breast-cancer link. The case was filed in the County Court of Victoria (Medical Division) No. 2000/06190

Many in the pro-choice movement try to deny the abortion breast cancer link by referencing an old 1997 Danish abortion breast cancer study published by Dr. Melbye that denies a link between abortion & breast cancer. The pro-choice movement argues that this study in Denmark is strong because it relies on national registries for abortion rates rather than relying on women to self-report. Please be advised that although abortions have been legal in Denmark since 1939, the Dr. Melbye's Danish abortion breast cancer study used computerized abortion records beginning only with 1973 rather than 1939. This is an enormous flaw that skews the results. The researchers understate this weakness of the study, acknowledging only that "we might have obtained an incomplete history of induced abortions for some of the oldest women in the cohort." But a check of pre-1973 abortions shows that Dr Melbye misclassified some 60,000 women who had abortions as not having had any.

This Melbye breast cancer study, begins counting breast cancer cases in 1967, but did not start a consideration of abortions before 1973. This puts the cases of disease six years before the suspected exposure to the potential cancer-producing cause which is an obvious & incredible blunder. However, Melbye’s studies indicate a 3% rise in risk of breast cancer for every week a woman waits to have an abortion, until at 18 weeks gestation her risk rises to 89%.

To read further weaknesses of Dr. Melbye's study, please visit http://www.leaderu.com/ftissues/ft9705/opinion/brind.html#

Many pro-choice supporters argue research linking induced abortion to breast cancer is weak because of a "recall bias" claiming women are inaccurately report abortion if not afflicted with breast cancer. This argument has also been refuted at http://www.abortionbreastcancer.com/letters/kahlenborn/index.htm

American Association of Pro-Life Obstetricians & Gynecologists also state on its website that their belief is that the National Cancer Institute (NCI) has been particularly strong in opposing any suggestion that there is an association between induced abortion & breast cancer. The American Association of Pro-Life OBGYN feels that NCI has taken certain liberties with their interpretation of the scientific literature and feels these liberties lack basic fairness and balance in NCI reaching their “no association” conclusion.

Cornell University's website also provides a presentation & information on breast cancer that is consistent with the assertion that induced abortion is associated with elevated breast cancer risk at http://envirocancer.cornell.edu/presentations/lifestyle.cfm

Here is an explanation of how induced abortion elevates breast cancer risk:

Delaying the birth of a first child significantly increases breast cancer risk because the childless woman has immature, cancer-vulnerable breast tissue - Type 1 and 2 lobules where 95% of all breast cancers are known to develop. A pregnant woman's breast tissue does not mature into cancer-resistant tissue until the last months of a full term pregnancy. By the end of a 40-week pregnancy, 85% of her breast lobules are mature, cancer-resistant lobules known as Type 4 lobules.

The most cancer-resistant tissue, types 3 and 4 breast lobules, only develops during the third trimester of pregnancy. During the first two trimesters, estrogen stimulates cell proliferation and lobule formation. However, starting at 32 weeks gestation, there is differentiation of breast tissue, resulting in a decrease in the number of terminal end buds, increased lobular development, and a termination of the proliferative process. Type 3 breast lobules average 80 ductules or alveoli per lobule. Type 4 lobules are milk-producing. This accounts for the fact that women who have premature deliveries before 32 weeks double their breast cancer risk.

Type 1 and 2 lobules grow faster in vitro than Type 3 lobules, have a shorter doubling time than Type 4, and have higher DNA labeling indicies than do Types 3 and 4 lobules. Type 1 lobules are terminal ductal lobular units. This is where ductal cancers develop. Parous women with breast cancer have a greater percentage of Type 1 lobules than do parous women without the disease.

Women have the greatest number of Types 1 and 2 lobules and are the most vulnerable to carcinogens during the time between menarche and the birth of a first child. Due to the proliferation of lobules during the first two trimesters, the woman who has an induced abortion is left with more Types 1 and 2 lobules than she had before her pregnancy began. This leaves her with more places for cancer to start. By contrast, the woman who has a full term pregnancy is left with more mature, cancer-resistant Types 3 and 4 lobules than she had before her pregnancy began. This results in the protective effect of a full term pregnancy. To read more: http://www.bcpinstitute.org/physiology.htm and http://www.abortionbreastcancer.ca/DearDoctor.pdf
