Which cancer? There are many. Cure, as "all forms of cancer, at all
stages, in vivo, in 50 years" -- overwhelmingly improbable. We'll be able
to lick/delay a lot of them, if diagnosed early, and using a personalized
adaptive screening/therapy, though.

Medical nanotechnology is very difficult. A much hairier problem than
"merely" making self-rep capable nanorobotics. I don't expect to live long
enough to see it, barring unforeseen advances in conventional life
extension, or an extremely fast ramping up of capabilities,
Singularity-style. I'm not expecting to see them both in my lifetime
(aforementioned 50 years, or so).

Duh. Needed to be said, though, as some people seem to miss it. Current
cryonics has an overpowering aftertaste of snake oil, alas.

Alas, it doesn't work so well in the geriatrics wards.

There's definitely a ceiling for biology (a healthy human with good
genetic endowment on CR, etc). There's zero evidence that that ceiling is
growing at a perceptible rate.
