[Stereotaxic breast biopsy techniques have become the standard of care for mammographically suspicious lesions].
An optimal technique for the evaluation of nonpalpable, suspicious mammographic lesions should have a low technical failure rate, no false-negative results and should remove the lesion completely. Since most of these lesions are benign, the procedure should be carried out in an outpatient setting without general anesthesia. Cancer is missed in 2.6% of cases with excisional biopsy following needle localization. Furthermore, 50-83% of these patients undergo a second surgical intervention for definitive surgical treatment. In contrast, the rate of missed cancers is less than 0.7% following stereotaxic core or large-core biopsies. However, using these techniques, discordant results and histologic high-risk lesions need to be recognized and reexcized. The cost-effectiveness of stereotaxic vacuum-assisted core biopsy has been demonstrated. Stereotaxic breast biopsy techniques such as vacuum-assisted core biopsy and large-core biopsy for suspicious mammographic lesions have low false-negative rates and result in few histologic underestimations.
