Ten years ago, Dr. Chris Kahlenborn, authored the book Breast Cancer: Its Link to Abortion and the Birth Control Pill, which established the connection between the birth control pill and breast cancer.

Now, a federal study confirms that data.

The study shows a strong connection between the use of oral contraceptives and a particularly aggressive form of breast cancer with a high mortality rate, known as “triple-negative” breast cancer (TNBC). The study also found that the connection was highest among women who began using oral contraceptives while they were teenagers.

The 2009 Jessica Dolle study of the Fred Hutchinson Cancer Research Center appeared in the April 2009 issue of the cancer epidemiology journal Cancer Epidemiology, Biomarkers and Prevention.

The research showed that women who start using oral contraceptives before the age of 18 multiply their risk of TNBC by 3.7 times. Recent users of oral contraceptives within the last one to five years multiply their risk by 4.2 times.

Furthermore, the study is noteworthy because it contained an admission of the link between abortion and breast cancer by National Cancer Institute (NCI) researcher Louise Brinton, who had previously influenced the agency to deny an abortion-breast cancer link.

The study showed a 40% risk increase for women who have had abortions, and one of the study’s tables listed abortion as a “known and suspected risk factor.”

Dr. Joel Brind, professor of biology and endocrinology and deputy chair for biology at Baruch College, City University of New York, described both findings a “bombshell.” Brind provided an analysis of the study.

Although the data’s been available for nine months, observers wonder why the mainstream media and cancer groups have been silent.

“Although the study was published nine months ago, the NCI, the American Cancer Society, Susan G. Komen for the Cure and other cancer-fundraising businesses have made no efforts to reduce breast-cancer rates by issuing nationwide warnings to women,” said Karen Malec, president of the Coalition on Abortion/Breast Cancer. “Obviously, more women will die of breast cancer if the NCI fails in its duty to warn about the risks of oral contraceptives and abortion and if government funds are used to pay for both as a part of any health-care bill.”
