Abstract:
Evaluation of breast masses is a frequent dilemma encountered by a primary care physician. Adding fine-needle aspiration biopsy to the work-up of these lesions adds an inexpensive, highly accurate test with high patient acceptance. At our institution a technique using a butterfly needle has yielded a sensitivity of 91% and a specificity of 100%.
