The type of biopsy is one of those choices which is best for you. A core biopsy is less invasive. With the assistance of xray they go in with a big bore type of needle or cone knife and remove part of the suspicious area.
With an excisional biopsy after dye localization. Using the assistance of mammogram the radiologist inserts a wire to inject dye to the suspicious area. The surgeon then goes via incision and removes the dyed are taking the specimen back to the radiologist to make sure by xray assistance again that the entire suspicious area us removed.
I had my biopsies in 2003, 2005, and 2008 each by incisionsl biopsy to me it was peace of mind I knew the day of the procedure the results as my surgeon had a pathologist reading it while I was recovering from the anesthesia and he knew that he had clean margins. He removed the entire suspicious are. You can read my personal experience at http://home.roadrunner.com/~amj. I take you from my initial abnormal mammogram, the biopsy, surgery and recovery period. With a reflection a year later.
Hope this helps. The more information you have the easier it is to decide what us best for you. Ask questions to the doctors and the nurses, what would they do how did patients handle the procedure. As my doctor said educate yourself. Be your own advocate for your care
