I'm 52, and starting to do the Dr. go-round. You know, they send you you 'round and 'round for test after test. I informed my kids of the first go'round out of obligation, but I'm wondering wherein that stops? I'm in the "questionable" position after a first CT scan and my DR. said wait 6 mos. and repeat, so I'm not really scared at this point. But my kids are. What do you all tell your kids and when?
