Hi! After two mammograms, I had A stereotactic core needle biopsy because there was micro calcifications in my left breast in one spot. I actually had it the same day I went back for a second mammogram….I felt their urgency. I had a breast reduction 8 years ago…can that cause micro calcifications? and if so, are they usually benign? I had the biopsy on Thursday but told them to wait until next Friday to let me know the results….because I am going on vacation and do not want to ruin the family trip if it is positive….
