what nationality are you? Some of your lingo is throwing me off.

Im dont know what an afe is, but ive never heard of cat scans increasing the risk of cancer. That doesnt mean it doesnt. I just havent heard that it will. I hope not as ive had 3 at this point.

If your british, maybe your doc is trying to cut down on national health services spending? idk, im going to go lay down.
