I don't see it happening. There's WAY too much money to be made with Cancer. If there ever is a "cure", only the richest people will be able to afford it.
Yeah I find it hard to be optimistic about the fight against cancer. Every other week it seems there's some breakthrough that you never hear about again and everyone is still dying.
And that's saying nothing about the likelihood that there are people out there who don't want cancer to be cured.
