An x-ray mammography apparatus has a stereotactic biopsy unit having two holders for a biopsy needle, the holders extending parallel to the exposure plane. The free ends of the holders, in which the needle is retained, each have a releasable closure for the needle, so that the biopsy needle can be detached from the holder while remaining inserted in the breast. This permits the patient to be moved away from the mammography apparatus, for example into an operating room, with the needle remaining in place as a means for identifying the location for surgery.
