Besides, what the heck does "a good chance" mean? You sound like a bookie.

I never said there was a cure for those cancers. I said => 'Get cured of a horrible cancer, and there's a good chance of living a full natural life. Happens all the time.'
The rest of your post does not get any better, so my advice is that you take a Mulligan.
