How many medical tourists are people with no connection to the host country purely there to find cheap care? My impression is that medical tourism is more talked about in America than practiced. The subtext to healthcare discussions in the US always seems to be that no matter how bad things are in America, healthcare elsewhere must be a disaster. Also, Americans either have health insurance or they tend not to be in a position to pay at all, even if the procedure is significantly less expensive than at home.
