ULTRASOUND-GUIDED BIOPSY
This is a biopsy technique of the breast using ultrasound (as opposed to x-rays). This technique is usually used to sample anything other than microcalcifications. The patient lies supine (on her back) during this biopsy. Because most people more comfortable being on their back for a long time (compared to being on their belly), patients usually favor this technique over stereotactic biopsy. This is performed with local anesthesia and, for most patients, results in little pain.
