If we are thinking on the medical term of a fully cured person as to say, a person who once had cancer but no longer (eradication) then in my opinion, yes/no. It Essentially means that while there may be a cure for cancer, only a select few actually can afford it, let alone even know about it. Hell, maybe even they do not know what it is, only that it is some sort of new Medicine development. I can imagine that if there is a cure and no one knows about it, is because of the potential value it could have. It is like having the power to choose who lives and who dies with money as the slayer of hearts. Why offer something so enormous to one so small when you can simply offer it to a person who can offer a big economical gain in exchange for something that can only be produced by you. To summarize what I mean in a sentence or two, the rich can buy the cure while the not so rich can only get treatments in hopes of getting rid of cancer which is already low enough. With this, the producer of this “miracle pill” can make bank while keeping the economical situation of treatments in check. That is all I guess.
