Thanks for your responses so far.
Passing thru, I have read that same research but considering that the first tumor was unpalpable although bigger than a grape, and that a calcification is often thought to be a precancerous condition, I will take the radiation risk over the one that may be brewing in my genes any day!!!! I feel like the mammos found that tumor long before I would have been able to feel them, and I didn't want to be like Mom and find them when it was way too late, (although she did live through it, she beat the odds I believe).
colleen10, thanks for your input, I really think that a benign tumor has the capability of becoming a bad one, and although not everyone agrees with that opinion, thanks for the info, it makes me feel better about my own self care plan.
KMcH, I'm glad to know it's not a dumb question!!!!! And how's that baby????
