Treating cancer is one thing - ensuring that we never get it should be the focus and that is quite easy to do.
They can't make money from us if we aren't sick - that's one of the main reasons that we have cancer. Our government and corporations have been poisoning us and giving us cancer for over 100 years and they have known it all along. They've known it since at least 1808.
Cancer is largely avoidable. Not completely, there are exceptions. Cancer is predicted to jump by 50% in the next 10 years - we should be asking why.
