We've been making artificial cells for quite some time, but they're purpose is more of a model than anything else. A way for us to study what happens when you take away everything and just start from the very basics. What you're talking about sounds more like artificial tissues and organs, which is an active area of study, although I don't immediately see how we might "engineer-out" cancer. There exists a world in which we develop tissues that age slower, but the more likely (not that it's happening anytime soon) scenario is very cheap organs that we can swap out for ours.
