Image-Guided Core-Needle Breast Biopsy Is an Accurate Technique to Evaluate Patients With Nonpalpable Imaging Abnormalities

An IGCNBB that demonstrates atypical hyperplasia or carcinoma in situ requires WLEBB to define the extent of breast pathology. Mammographic surveillance for a patient with a benign IGCNBB is supported by nearly 100% specificity. An IGCNBB diagnosis of invasive carcinoma is also associated with nearly 100% specificity; therefore, these patients can have definitive surgical therapy, including axillary dissection or mastectomy, without waiting for the pathologic results of a WLEBB. Based on the authors' findings, IGCNBB can safely replace WLEBB in evaluating patients with nonpalpable breast abnormalities.
