This video succinctly describes stereotactic core needle breast biopsy. The presentation discusses the fact that stereotactic core needle breast biopsy is an outpatient procedure, relatively painless, and with few side effects. It demonstrates the technique on a real patient, simply explaining chat the procedure is done by taking two separate X·rays of the breast to locate the lump, and then, with only local anesthetic, using a needle to obtain a tissue sample. The information patients need is provided in a reassuring manner.
