Yesterday my little sister{35} calls me to tell me that the drs want her to come in...there is something on her first mamogram that they don't like.Today we go in for a sonogram.We are totally clueless.No family history of any type of cancer.What are we preparing for? Any advice on questions we should ask ? Premature, I know because we have no info at all at this point....but.Disbelief is high,but still any help would be appreciated.Thanks!
