Breast intervention: how I do it.

Breast imaging has undergone many changes since the early years of mammography. Screening mammography is credited with contributing to the substantial decrease in breast cancer mortality through early detection. Screening mammography programs allow depiction of nonpalpable, suspicious findings requiring histologic evaluation, but most of which eventually are proved benign. Widespread acceptance of percutaneous breast biopsy techniques represents the most important practice-changing development in breast imaging. The radiologist now plays a vital role not only in the detection and evaluation of breast disease, but also in the diagnosis and management of breast cancer. Descriptions of the advantages of percutaneous breast biopsy and the techniques of performing breast intervention are the focus of this review.
