Hi, I had a core biopsy on Wednesday to determine if tissue in my breast that looked "pulled", was something to worry about or not. The Dr. taking the scan said it was a 50/50, she couldn't figure out if it was something that needed to be investigated or it was ok, and erred on the side of caution. It was "different" from my last x-ray, that's what they said. I don't go back for results until next Tuesday afternoon, and I can't sleep, because I have no clue as to weather I should be looking up the internet for chances that I have breast cancer!
