Oddly enough, from memory, I believe KSR's characters cure cancer as well. But on the surface of Mars. Can't remember how!
The way I'm thinking of it, cancer hasn't been cured, there's just a whole lot less of it, because they've figured ways to deal with different types of cancer. It's kind of like the common cold, there are lots of different kinds of it. But the clean tube was made to deal with medical problems like that originally.
They used it to help people go on long trips through space later on.
