The diagnosis of breast lesions is frequently difficult and proving malignancy before treatment is of great importance. Fine needle aspiration biopsy is one of the three components of the triple test (the other two being the clinical examination and mammography or ultrasound). The present paper presents and correlates the value of ultrasound guided fine needle aspiration biopsy with the type of lesions. There are discussed the advantages of this diagnosis test performed under ultrasound guidance compared with the clinically guided fine needle aspiration biopsy and the value of the diagnosis test in reducing open surgical procedures.
