It's possible...I've heard cancer is extremely hard to detect, and only becomes comparatively easier to detect when it's too late. Maybe he was lucky, discovered he had cancer, and didn't want to waste his time.

Alas, we don't really have evidence about that, do we? A damn lot of people die young, it could have simply been pure paranoia towards death what drove him to follow that "Fast is Important" belief.
