Wagglebee - there’s plenty of evidence out there if you were to look. I just pulled up the first four I came to using search: “breast cancer” abortion link.

I know that, Phantom Lord was the one who questioned the validity of post-abortion health risks.
One of you links was the “Feminist Women’s Health Center” which I would hardly call an “impartial” source. They also provide all sorts of abortion information.
