No one at this point can say specifically that abortion does or does not cause breast cancer. More studies need to be done. Surprising that with the work that has already been done in this field that pro-womens groups like PP and NOW politically demand nothing. Are they afraid that if information leads to the conclusion that abortion does cause BC that abortion laws will be overturned? They would rather woman have the choice to kill than any chance to cure BC. It's all about denying women the choice, to be informed. For them its to risky to even inform women about the links that abortion has to Breast Cancer.
