View in Spanish: Biopsia por colocación de aguja

Needle-localized biopsy (NEE-dul LOH-kuh-lized BY-op-see)
A procedure to mark and remove abnormal tissue when the doctor cannot feel a lump. An imaging device is used to guide a thin wire with a hook on the end through a hollow needle to place the wire in or around the abnormal area. Once the wire is in the right place, the needle is removed and the wire is left in so the doctor will know where the abnormal tissue is. The wire is removed at the time the biopsy is done.
