Breast Biopsy
Open Excisional: a small incision (cut) is made as close as possible to the lump and the lump, together with a surrounding margin of tissue, is removed for examination. If the lump is large, only a portion of it may be removed.
Fine Needle Aspiration and Core Needle Biopsy: both these procedures involve inserting a needle through your skin into the breast lump and removing a sample of tissue for examination.
