How Does Induced Abortion Raise Breast Cancer Risk?

Font size: Decrease font Enlarge font

In the pink month - the National Breast Cancer Awareness Month, we'd like readers to know something that many women may not have learned from any other source, and that is, induced abortion increases risk of breast cancer. 

Be aware, especially in the National Breast Cancer Awareness Month that the association between induced abortion and breast cancer risk is not only a subject of medical science, but also politics.  We encourage readers to do their own home work and make their own scientific conclusion on this subject.

Dr. Angela Lanfranchi, Clinical Asstistant Professor of Surgery at Robert Wood Johnson Medical School, Piscataway, N.J. kindly wrote a short article below for foodconsumer readers to help them understand why induced abortion raises breast cancer risk.

Those who want to know more on the abortion-breast cancer link are advised to read an excellent review authored by Dr. Lanfranchi, which is available at http://www.bcpinstitute.org/2009-Lanfranchi-LinacreQuarterly[1].pdf

How does induced abortion raise breast cancer risk?

A growing amount of evidence from quality studies suggests that induced abortion, but not spontaneous abortion or miscarriage, increases risk of breast cancer.

Of course, induced abortion is not the only risk factor for breast cancer. Most women diagnosed with breast cancer have never had an abortion. Most women who have had an induced abortion will not get breast cancer. Like a family history of breast cancer, which is involved in about 15 percent of all breast cancer cases, induced breast cancer is just another risk factor.

Cigarette smoke is a carcinogen. While only 15% of cigarette smokers get lung cancer, the risk has been well acknowledged.  In comparison, induced abortion as a risk factor for breast cancer is somehow not as widely publicized.

Induced abortion boosts breast cancer risk because it stops the normal physiological changes in the breast that occur during a full term pregnancy and that lower a mother’s breast cancer risk.  A woman who has a full term pregnancy at 20 has a 90% lower risk of breast cancer than a woman who waits to age 30.

Breast tissue after puberty and before a term pregnancy is immature and cancer-vulnerable.  Seventy five percent of this tissue is Type 1 lobules where ductal cancers start and 25 percent is Type 2 lobules where lobular cancers start.  Ductal cancers account for 85% of all breast cancers while lobular cancers account for 12-15% of breast cancers.

As soon as a woman conceives, the embryo secretes human chorionic gonadotrophin or hCG, the hormone we check for in pregnancy tests.

HCG causes the mother’s ovaries to increase the levels of estrogen and progesterone in her body resulting in a doubling of the amount of breast tissue she has; in effect, she then has more Type 1 and 2 lobules where cancers start.

After mid pregnancy at 20 weeks, the fetus/placenta makes hPL another hormone that starts maturing her breast tissue so that it can make milk. It is only after 32 weeks that she has made enough of the mature Type 4 lobules that are cancer resistant so that she lowers her risk of breast cancer.

Induced abortion before 32 weeks leaves the mother’s breast with more vulnerable tissue for cancer to start. It is also why any premature birth before 32 weeks, not just induced abortion, increases or doubles breast cancer risk.

By the end of her pregnancy, 85% of her breast tissue is cancer resistant. Each pregnancy thereafter decreases her risk a further 10%.

Spontaneous abortions in the first trimester on the other hand don’t increase breast cancer risk because there is something wrong with the embryo, so hCG levels are low.  Another possibility is that something is wrong with the mother’s ovaries and the estrogen and progesterone levels are low. When those hormones are low, the mother’s breasts do not grow and change.

A woman can use this information to make an informed decision about her pregnancy. If she chooses to abort her pregnancy for whatever reason, she should start breast screening about 8-10 years later so that if she does develop a cancer, it can be found early and treated early for a better outcome.

If she doesn’t have the resources to raise a child or is not ready to be a mother, there are millions of couples waiting to adopt any child, even one with disabilities.

Women need to understand their own bodies so that they can make the best decision for themselves.

Here's a crazy, wild theory. Maybe there's a "milk fungus" that produces toxins that can cause cancer. It could work in conjunction with a virus as well. Shouldn't we have solved this problem already? After all the years and all the money we've spent, we're not any closer to a cure. If we put as many resources to work to cure cancer as we did to develop the atom bomb, we would have cured it already.

In this world of publish or perish this the insane theory.It is the synthetic estrogen hormone which causes much problem as it is not biodegradable.Is it casual or causal association.At the end reader beware.

Every medical organization but the Catholic league officially states that there is no causal link between abortion and breast cancer.

This article is lies and speculation.

In short, bullshit. You can dress this up as you being concerned about people's health but this is nothing more than propaganda for pro-lifers. Please, you should voice your opinion on moral and ethical issues. But if you are lying to people, you're not being very moral yourself now are you?

You people that are pro-abortion are amazing. Where do you get off refuting medical evidence without a shred of medical evidence to prove your point. Your arrogance based on your pro-abortion position is staggering. There are doctors studying the connection between induced abortion and breast cancer on the cellular level, all of your imput is purely based in a personally opinon in regard to abortion.

@ John.. Maybe if the largest foundation looking for a cure..Susan G. Komen would stop giving money to Planned Parenthood (largest single abortion provider) we might be closer to a cure.

I'm sorry Angela, but if disagreeing with bad science poised as propaganda makes you an arrogant pro-abortion jerk, then while I disagree with the label I guess that would be me. (Personally I prefer the term pro-choice. I have the respect to call people that consider themselves pro-life the term they'd prefer.)

That being said though, you're also saying this is true of the World Health Organization, the U.S. National Cancer Institute, the American Cancer Society, the American College of Obstetricians and Gynecologists, and the American Medical Association. Do you seriously think all of these groups of scientists and medical professionals are out to promote baby killing?

How about looking at all the mutated genes from the first 15 years of "the pill" prescribed to so many women. And/or hormone replacement advised to so many women by their physicians.

Robert...you wrote about the American Medical Association and asked whether they were "promote baby killing". Well I found some hard fact.

AMA supports taxpayer funded abortion.
AMA support partial birth abortion where the child is delivered (except for the head) and then cut up.
