Abstract:
Background
There is controversy regarding which of the two biopsy methods, fine-needle aspiration (FNA) or core needle biopsy (CNB), should be routinely employed for diagnosis of breast cancer. The aim of this study was to evaluate the efficacy of FNA compared to CNB and to explore the value of performing both FNA and CNB.
