I Am About To Have A Needle Biopsy For Dcis

I am about to have a needle biopsy for Dcis for microcalcifications. The biopsy will vacuum suction the microcalcifications and a titanium marker will be place in my breast. At that time I will be told if the calcium growths are benign or invasive. What are relevant questions to ask my doctor either prior to the biopsy or afterwards?
