>We're unlikely to find "a" cure for cancer; we'll eventually find "cures" for cancer, but it will be small, incremental steps.

I completely disagree. There will be a "cure", but it'll be a while, and it won't resemble current medicinal methods at all. I predict that in another century or so (assuming civilization doesn't collapse like the Roman Empire and send us into another Dark Age, but on a global scale), we'll basically become cyborgs, with nanites implanted in us to augment our natural bodily functions. These nanites, basically being nanoscale robots, would improve on or replace our immune systems, eliminating cancer, as well as most aging effects.
