Coalition Berates American Cancer Society for Withholding Cancer Evidence

The Coalition on Abortion/Breast Cancer notes an American Cancer Society report showing that cancer deaths declined slightly in 2003 and 2004. [1] 

Karen Malec, president of the Coalition, commented, "There would be fewer cancer cases and deaths if women had been told the truth in the 1980s when conclusive evidence became available showing that breast cancer is associated with combined (estrogen plus progestin) hormone replacement therapy [2], combined oral contraceptives [3,4,5,6], and abortion." [7,8,9,10,11,12]

The Society expects 40,460 female deaths due to breast cancer and 240,510 total breast cancer cases for 2007.

The Society misleads women about abortion-breast cancer research.  Its website says, "Several studies have provided very strong data that induced abortions have no overall effect on the risk of breast cancer." [13] 

It does not report that a scientific review in 2005 concluded that these studies are seriously flawed and cannot be used to dismiss the larger body of evidence supporting an abortion-breast cancer link. [8]  No scientist has challenged these conclusions.

"We call on the Society and other cancer businesses to put their priorities in order," said Malec.  "Women's lives and cancer prevention are more important than making money, doing cancer walks, and protecting the abortion and pharmaceutical industries."

The Society and Susan G. Komen for the Cure, give funds to Planned Parenthood, ostensibly for cancer screening, but Planned Parenthood is known for moving funds to the abortion side of its business. 

Malec argued, "More abortions and sales of hormonal contraceptives mean more cancer cases. It's unthinkable that groups that claim to want to eradicate the disease would help fund a cancer-causing organization, especially when the funds could be directed to legitimate health organizations."

"As far as breast cancer is concerned, the risk-reducing effect of full-term pregnancy has been well-known literally for centuries, and is universally acknowledged...It is hardly difficult to connect the dots here: Having an induced abortion leaves a woman with a higher long-term risk of breast cancer, compared to not having the abortion; i.e., compared to childbirth." [14] 

The Coalition on Abortion/Breast Cancer is an international women's organization founded to protect the health and save the lives of women by educating and providing information on abortion as a risk factor for breast cancer.
