Fine-needle aspiration biopsy (FNAB) is a minimally invasive diagnostic procedure that involves using a thin, hollow needle to extract cellular material or tissue from a lump or mass, typically for pathological analysis. It is commonly employed to evaluate masses in the thyroid, lymph nodes, breast, and other soft tissues to aid in diagnosing benign or malignant conditions.
