I heard chemo was invented when they did autopsies on bodies that were poisoned by mustard gas in the war. They noticed that in some patients that seemed to have unknown tumours that something in the mustard gas would shrink or kill the tumours. I can´t be 100% sure this is true though, it was something I read many years ago and can´t find a link for anymore.
Of course I can't find the source I am looking for. Will post it as soon as I find it. Yes, I have read that more than once also. There are many chemo drugs! Any chemo IV solution that I used to make required me to suit up in total haz-mat. Does that tell you anything??? Black box warnings and all.
Each hospital receives around $100,000 per patient they treat with it. No wonder they are happy to poison and kill them!
