Stereotactic breast biopsy: pitfalls and pearls.

Stereotactic breast biopsies have become indispensable and the standard of care for patients in whom screening mammography or tomosynthesis reveals breast lesions suggestive of malignancy. A variety of stereotactic biopsy systems and needle types are now available, which allow more accurate sampling of lesions as well as successful biopsy of lesions in difficult locations in patients of all body habitus. We discuss how to plan, perform, and follow up stereotactic biopsies. Most importantly, we offer suggestions on how to avoid problems and complications and detail how to achieve technical success even in the most challenging cases. Stereotactic biopsy has proven over time to be an accurate and acceptable alternative to surgical biopsy for histopathologic diagnosis of breast abnormalities. Successful performance of this minimally invasive procedure spares women from undergoing potentially deforming and expensive procedures to diagnose breast disease.
