[Fine-needle biopsy and core biopsy in nonpalpable breast lesions. How does one judge with mammography?].

Abstract

Techniques for localizing and sampling subclinical lesions seen on mammograms are reviewed. Localization of the lesion, the equipment used (fine-needle aspiration or core biopsy), and harvesting techniques are discussed, with special emphasis on quality criteria that should be satisfied to ensure optimal histologic performance.
