If you are a completely healthy person and you pay an outrageous amount of money for a full body scan you are a total twat.
Why you cry? "Isn't it a good thing to know that everything is OK and there are no lurking tumours or aneurysms waiting to kill you at any moment?"
No No No No No and again NO.
To quote the article "She had experienced no symptoms whatsoever, but it could have burst at any moment: the scan's locating of it allowed a relatively easy surgical fix."
But what, as would often be the case, there is no easy surgical fix. Then you have to live your life with a death sentence, would that make you feel better or worse do you think?
The other thing is that in the average middle-aged person the liklihood of having a normal scan is small. They would find little lumps and bumps which may or may not be dangerous. You will then be forced to have annual complete body scans to check if the innocuous lumps have changed or grown, making lots of money for the scan companies which is the aim of the whole bloody exercise.
Everyone who goes in for this sort of thing is seeking reassurance but not everyone will get it so think long and hard before subjecting yourself to an unnecessary investigation.
If however you are fascinated by scans and anatomy I can recommend Mr. realdoc's favourite site in the whole world, here. Marvel at the pretty pictures. I have a feeling that this is what he sees at moments of high emotion so wonderfully described by patroclus.
