uhm im not a scientist or a doctor but i have to disagree with you here you might have heard of the famous G. Edward Griffin who wrote the book on the federal reserve..? "The creature from jekyll island" he also wrote a book called "World without Cancer" in which he talks about cures for cancer ..:)
and there are also other alternative ways for healing cancer e.g. the great Dr. Royal Rife whos results got actually recreated recently there is even a TED talk about it
and if you want to learn about why there is so much resistence in the pharmaceutical industry id encourage you to watch this :)
