The only way to "prove" the link in a scientific sense would be to do studies where one cohort has an abortion, and one does not, controlling for other factors such as diet, smoking, drup use, exposure to environmental toxins, etc

How is this done? Would this person never eat fast food? Processed food? Live in a bubble with an oxygen tank? Never take man made drugs?

I will say it one more time. The average person ingests so much crap into their bodies that NO ONE can know what causes cancer. Anything and everything could be shown as a "link" due to there being an almost infinite number of variables(I say infinite because we do not know what may or may not cause cancer).

Well, so much for any credibility you had on this thread. You know NOTHING about epidemiology. Ignorance of basic science is a poor foundation upon which to build a rational debate.

Maybe you don't. But that ignorance shouldn't be paraded in a public forum. It hurts your side of the debate.

Ever hear of smoking causing lung cancer? How about HPV causing cervical cancer? Or Hep B causing liver cancer? What about radiation causing thyroid cancer? Chewing tobacco causing lip/mouth/throat cancer? DES causing breast cancer? Radon gas causing lung cancer? These are off the top of my head. Should I continue?
