China's one-child, forced abortion policy now reaping increased cases of breast cancer

Not exactly a great Mother's Day post, but this is information that you won't find in most media outlets:

China's one-child policy that forced women to abort any ensuing fetus now is resulting in an increase in the number of breast cancer cases.

These are legitimate studies published in peer-reviewed journals. Despite what the abortion industry (Planned Parenthood, etc.) along with research societies bulldozed by ideological extremists would have everyone believe, it is not "settled science" that there is no link.

Below is a commentary by the Coalition on Abortion/Breast Cancer, along with footnoted references. (The commentary also includes important information on a French study)

 COALITION ON ABORTION/BREAST CANCER 

COMMENTARY 

French Study 

A French study led by Julie Lecarpentier, which included the esteemed scientist, Nadine Andrieu of the Curie Institute, reported a significant trend among women with increasing number of abortions (P=0.02). [1]

In comparison to women with no incomplete pregnancies, the authors found a non-statistically significant 1.29-fold risk elevation among women with a history of induced abortion and a non-statistically significant 1.49-fold increased risk among women with a history of induced abortion and miscarriage.

Lecarpentier’s team reported atypical findings among women with BRCA1 and BRCA2 genes that differ from what scientists have reported for the general population. Although experts have long agreed an early first full term pregnancy before age 25 (the younger, the lower the risk) substantially reduces risk for the general population, BRCA1 and BRCA2 carriers benefit from delaying first full term pregnancy until ages 25-29. Nevertheless, full term pregnancy reduces risk for both populations.

For the general population, induced abortion raises risk, but most miscarriages (which primarily consist of abnormal first trimester pregnancies) do not raise risk. By contrast, in the case of BRCA1 and BRCA2 carriers, Lecarpentier’s team reported similar findings for both induced abortion (non-statistically significant 1.30-fold increased risk) and miscarriage (non-statistically significant 1.35-fold elevation in risk).

Professor Joel Brind explained, “This can be attributed to the fact that the risk elevation is limited to induced abortion before first full term pregnancy (statistically significant 1.77-fold elevated risk).”

Dr. Brind later added, “Bottom line: Unlike the general population, women who carry the BRCA 1 or 2 mutation benefit from having children later rather than sooner. However, while having a child when young does not confer any significant benefit (i.e. decreased risk), aborting an early pregnancy significantly increases risk (i.e., 1.77-fold risk elevation if abortion occurs before first full term pregnancy). Moreover, although induced abortion after first full term pregnancy does not increase risk relative to no abortion, it clearly increases risk relative to not aborting that pregnancy, as full term pregnancy becomes more and more protective with age in these women. So overall, these women are really not that much different, when one considers the real life situation of already being pregnant: Carrying the pregnancy to term always leaves the woman with a lower risk than would having the abortion.”

Chinese Study 

A hospital-based study on women in Yunnan province, China led by Che Yanhua reported a significant increasing trend with number of abortions (P=0.001). [2] In

comparison to never having had an abortion, one abortion was associated with a statistically significant 2.50-fold increased risk. Two or more abortions were associated with a statistically significant 12.31-fold elevated risk. The study likely produced an underestimate of the risk because its abortion numbers are diluted by a small percentage of first trimester spontaneous abortions, which don’t impact risk.

Karen Malec, president of the Coalition on Abortion/Breast Cancer said, “The corresponding author acknowledged to us by e-mail that, even though he and his colleagues did not distinguish between induced and spontaneous abortions, ‘Induced abortion is the main method of family planning used by Chinese people for (the) one child policy. Thus, induced abortion is the majority and encounters over 90% of the cases.’”

Yanhua’s team argued that recall bias “can have a significant impact on the precision of the information gathered. Cases with BC (breast cancer) in these studies may link abortion to BC by themselves and are likely to provide more complete or even biased information about their abortion history than controls without BC. Such differences in the completeness of reporting can compromise the accuracy of the study results.”

Their team provided no citations to support their argument. Western researchers have speculated about recall bias for years, without finding any credible evidence to date that more healthy women than breast cancer patients lie about or forget their abortions. In a nation where a one child policy is vigorously imposed on the population, women are unlikely to be ashamed to reveal their abortion histories.

Additional reproductive risk factors for breast cancer found in the study include: delayed first full term live birth until age 24 or older (statistically significant 1.82-fold elevation); lack of breastfeeding after birth (statistically significant 3.26-fold elevation); and childlessness. One birth decreased risk by a statistically significant 91% in comparison to childlessness.

“Of course, more abortions mean more delayed first full term pregnancies, less breastfeeding, more childlessness, and smaller families,” observed Mrs. Malec.

“The Chinese counterpart to America’s Roe v. Wade Generation - which, according to the 2001 Annual Report to the Nation on the Status of Cancer, suffered the brunt of the increased incidence of breast cancer (not the two older generations that did not have legal access to induced abortion) - might be called the ‘One Child Policy Generation,’” mused Karen Malec, president of the Coalition on Abortion/Breast Cancer. [3] “At least two studies have fingered China’s one child policy for being at least partially to blame for an approaching epidemic in 2021 of 2.5 million breast cancer cases among women aged 35-49 years in 2001.” [4,5,6]

Yanhua et al. 2012 is the eighth of eight Chinese studies linking induced abortion with increased breast cancer risk. Excluding a 2007 ecologic study on eight European countries finding that induced abortion was the “best predictor” of future breast cancer

rates, 55 of 70 epidemiologic studies report risk increases for women with abortions. [7,8]

This birth-control policy introduced into Shanghai in 1974, resulted in a fall in birth rates particular in early fertility. The one-child rate in urban Shanghai increased to 90.5% in 1978 and this status has maintained at a high level of 99.5% in the following years. Total fertility rate has remained the lowest in the world, at 0.81 in 2006, lower than that in the most industrialized countries. When birth cohorts are considered, post-1950 cohorts would be involved in birth-control policy and they are also the cohorts related to the incidence boom. This observed trend supports the hypothesis that the alteration of reproductive factors by birth control policy exerts its effect on the middle-age group.” [Fan L, et al.

By 2021, 2.5 million women aged 35-49 years in 2001 are expected to have breast cancer. China is ‘on the cusp of a breast cancer epidemic’ (Linos et al. 2008).” [Liu C.-Y. et al.

Here is more commentary:

 

The Chinese government reports that female breast cancer deaths climbed nearly 40% in the last decade and that the disease is impacting a younger age group - women between the ages 45 and 49.

Similarly, American women suffered a more than 40% increase in breast cancer cases between the mid-1980's and 1998, and the increase took place entirely within the Roe v. Wade generation - the group of women who were under age 40 in 1973 when abortion was legalized. [1] According to the "Report to the nation on the status of cancer, 1973-1998," the two older generations which didn't have access to legalized abortion did not experience this increase in breast cancer rates.

According to Angela Lanfranchi, MD, FACS, Associate Professor of Surgery at the Robert Wood Johnson Medical Center, abortion made breast cancer a young woman's disease.  It used to be a grandmother's disease.

The Chinese government, like the American government, isn't telling women why they're getting more breast cancers.  Here's a little clue for the Chinese and U.S. governments. Nations that prohibit abortion (like Ireland and Poland) have significantly lower breast cancer rates. [2]

Two seriously flawed Chinese studies have been used to convince American women that abortion will not increase their odds of developing breast cancer. [3,4] Drs. Joel Brind and Vernon Chinchilli sent a letter last year to the British Journal of Cancer citing flaws in the Chinese studies. [5]

Scientists know perfectly well that there's no comparison between the childbearing practices of Chinese and American women. Americans choose their abortions. Chinese women don't.  China has a one-child per couple policy.  Women who become pregnant illegally are forcibly aborted.

Abortion is prevalent in China because of the one-child per couple policy. Chinese women have early first full term pregnancies, and subsequent illegal pregnancies are forcibly aborted. Scientists agree that having an early first full term pregnancy (the earlier, the lower the risk) significantly reduces breast cancer risk.

By contrast, American women generally choose abortion before the birth of a first child, so Americans have their abortions during the most carcinogenic time in a woman's life. Childless women have immature, cancer-vulnerable Types 1 and 2 breast lobules. Starting early in pregnancy, women are overexposed to the hormone, estrogen, a carcinogen that stimulates the lobules to multiply and causes the breasts to grow.  Only one event protects women from estrogen, shuts off cell multiplication and matures their breast tissue into cancer-resistant, milk-producing Types 3 and 4 lobules - a third trimester process in pregnancy called "differentiation."

Because abortion is so widespread in communist countries, it's difficult for scientists to find adequate control groups in these populations. Accurate epidemiological research becomes more difficult when a majority of the population has been exposed to abortion.

In such a case, women who don't have abortions become a minority, an atypical group - women who never married or who married late in life. These circumstances typically cause women to delay their first full term pregnancies or to be childless.  Both groups are at high risk for the disease.

Hence, the Chinese studies underestimate the relative risk of abortion because they compare women who received the protective effect of an early first full term pregnancy with women in a high-risk subgroup. The risk-reducing effect of early first full term pregnancy masquerades as the risk-reducing or null effect of abortion.

China is gearing up for a dramatic surge in breast cancer cases. The government couldn't have come up with a better population control plan.

  • I have heard of the increased rate in breast cancer in asian countries, but it has been attributed to the increase in dairy products and the western diet.
