Re: early mammogram ?
It would probably be a good thing to get a baseline when you know all is clear. Then the would have soemthing to compare it to later. I wish they would do that with bone density scans. My doctor is on my case about mine but I maintain I've always probably been this way as I am a petite white female. Since they don't do them till you're menopausal, how do they know if anything has changed? Heck, you're in your 50's by then!
And no, the radiation isn't a problem.
