Study of 36 Chinese Abortion-Breast Cancer Studies a “Game Changer,” Says Scientist

12/3/2013

The following statement was released by the Coalition on Abortion/Breast Cancer on Dec. 2, 2013.

A systematic review and meta-analysis of 36 Chinese studies, published by Dr. Yubei Huang and his colleagues in the prestigious journal Cancer Causes Control, last week reported a significant 44 percent increased breast cancer risk among women with at least one induced abortion (IA), compared to women without induced abortions.[1]

The risk increased with number of IAs (a dose effect), an important measure of a cause-effect relationship. Having two and three IAs raised risk by a statistically significant 76 percent and 89 percent, respectively. Earlier studies also found a dose effect.[2,3,4,5]

Huang’s team cited and supports a 1996 review and meta-analysis led by Dr. Joel Brind and colleagues at Penn State[6], who found a 30 percent risk elevation for women with any history of IAs. Huang’s team agreed with criticism from Brind and Dr. Vernon Chinchilli in the British Journal of Cancer[7] concerning two high profile Shanghai studies.[8,9]

In his analysis of the Chinese study, Brind called it a “game changer.” He said, “Not only does it validate our earlier findings from 1996, but its findings are even stronger, for several reasons.”

Significantly, Brind argued that insurance under Obamacare funds abortion and contraceptive steroids (i.e. the Pill) which will be disastrous for women’s health.

Huang’s team said their results differed from those of a 2004 meta-analysis by Dr. Valerie Beral and her colleagues.[10] Beral’s paper, which claimed there was no link between induced abortion and breast cancer, received harsh criticism in seven medical journals from four experts independently of one another.[11,12,13,14,15,16,17]

Karen Malec, president of the Coalition on Abortion/Breast Cancer, said, “Our organization and the Breast Cancer Prevention Institute — which Dr. Brind co-founded — are among the groups that collaborated on an amicus brief in three lawsuits against Obamacare’s contraceptive mandate.[18] Last month, a federal appellate court cited the brief which reports the World Health Organization’s classification of the Pill as a Group 1 carcinogen; and the U.S. Supreme Court announced it would hear those lawsuits.”[19]
