An improved method for localization of nonpalpable breast lesions.

Insertion of a hooked stylet into the region of a mammographic abnormality is a simple method of localization prior to biopsy. The hook on the stylet does not permit movement of the localization device away from the lesion during the interval between placement and surgical excision. A xeroradiograph of the biopsy specimen determines whether the suspected region was obtained surgically.
