Is there such thing as a full body scan?

Well, the best test that you can have now would be a full-body MRI. I don't know how much it would be, but everything in medicine is very expensive these days. If you have the money to pay for it, then there will be a doctor out there willing to perform the exam. Your best bet would be to seek out the most affluent community (or communites) in your state. Go to a local pharmacy in the affluent town and find out who the best doctor or practice is in town. Set up an appointment (if they're taking new patients) and take it from there. I know this sounds crazy, but trust me. I've worked in pharmacies in low-income neighborhoods and I worked for a pharmacy in an extremely affluent community in Connecticut and there IS a dramatic difference in health care. The doctors of affluent communities basically cater to their patients and give them just about anything they want, within the limits of the law, of course.
