You may have heard ads for those "full body scans", but what are they, what are they for, and how do they work?They're the sort of thing your insurance doesn't pay for, because they are preventative and entirely elective. They earn the hospital great money because they aren't priced according to deep-discounted insurance pay matrices, and since they're non-emergency, they can schedule it conveniently.
That doesn't mean it's a bad thing. A scan checks you for any and everything you may be sick with, and it can catch serious illnesses while they're in such early stages that your cure rate is vastly improved.
You don't "need" a scan, but especially if you're a hypochondriac, it will either put your mind at ease or prove to you that you've always been right. Just make sure you can afford it, shop around for the best price, and give it consideration.
