So apparently, since the original study was conducted to examine the link between diet and breast cancer, and no such link was discovered, they somehow felt justified to omit the fact that having an abortion increased a womans chances of contracting breast cancer by 160%, since that wasn't a diet related factor.
These were obviously not truth seeking scientists. They had an agenda to push, and fatty foods figured into it. When they discovered the truth about abortion and breast cancer, they buried it. Not true scientists (truth seekers) in the classical sense.
I encourage you and others here who wish to expose junk science and the political agenda of pseudo scientists like Dr. T.E. Rohan, to copy and save this abstract, and try to get a copy of the original article. It is available at university libraries and research hospitals. You may be able to get a reprint from AJE.
