DALLAS--Fine-needle aspiration (FNA) breast biopsies in women with mammographically apparent, nonpal-pable breast lesions were deemed impractical due to the high rate of insufficient samples in a Radiologic Diagnostic Oncology Group (RDOG) study, and were stopped 19 months into the trial, Etta D. Pisano, MD, said at the American College of Radiology (ACR) National Conference on Breast Cancer.
