... We know with absolute certainty that oral contraceptives (OC's) and abortion both raise a woman's risk of developing breast cancer. Renowned breast surgeon Dr. Angela Lanfranchi of the Breast Cancer Prevention Institute, along with City University of New York Professor of Endocrinology Dr. Joel Brind explain the mechanism:
Prior to a first full term pregnancy (FFTP) the cells that comprise the lobules of the breast are immature and cancer-prone Type 1 and Type 2 cells. Under the influence of the high levels of estrogen in OC's and during pregnancy, the lobules of the breast roughly double in number. This results in a doubling of the number of cancer-prone Type 1 and Type 2 cells. In pregnancy, it isn't until the third trimester under the influence of the hormone human placental lactogen that the immature cells mature into cancer-resistant Type 3 and Type 4 cells.
... The science is clear that the earlier a woman bears children, and the more she nurses, the greater her protection from breast cancer. The science of the past fifty years is also abundantly clear that having an abortion prior to a FFTP allows for the proliferation of the cancer-prone Type 1 and Type 2 cells, while terminating the pregnancy prior to the onset of the third trimester's protective mechanism that converts these cells to the cancer-resistant Type 4 cells leads to increased incidence of breast cancer. The risk of breast cancer in women having an abortion prior to a FFTP ranges from 40% to 90% in most cases. In girls under the age of 18 with a family history of breast cancer the risk becomes incalculably high.
Other institutes devoted to getting the word out about breast cancer in relation to OC's and abortion are the Polycarp Research Institute, under the direction of Chris Kalenborn, M.D.; and The Coalition on Abortion/Breast Cancer, under the direction of Ms. Karen Malec. Malec's website is loaded with links to the scientific data and refutations to the lies told by pro-abortion apologists such as Dr. Louise Brinton of the National Cancer Institute whose own research through the years has shown the link between abortion and breast cancer, and who convened a panel in 2003 to deny the validity of fifty years of research showing that link....
