I don't know of this specific story, but one thing that House MD tried to drive home at some point, and which my acquaintances in med school confirmed, is that you don't want to do full-body scans without a very good reason, because a full-body scan on a typical adult will always find something. That something will most likely be harmless, but for various reasons, once you know it's there, you'll end up trying to do something about it, and the combined impact of stress and treatment on health may be much worse than if that thing was just left unseen. This thinking, I've heard, applies to many other ideas of running speculative imaging or blood tests. For some reason it does not apply to ultrasound - I hear many doctors are in favour of patients getting ultrasound twice a year or more often, but I don't know what's the rationale.
