Medicine: is a CT scan going to kill you?

Probably not.

Articles like this have been floating around like nuts lately about the increase of cancer mortality for those who undergo full-body CT scan. Don't buy it. There are some definite methodological issues here, as well as no discrimination as to who is getting the CT scan. If your doc is sending you for a CT so he can make a payment on the machine he and his 12 partners in their private practice decided to buy last year, then that might be problematic. But otherwise, it's a little better to get the CT than play guessing games w/ your guts. Cuz that probably will kill you.
