Fine needle aspiration biopsy in diagnosis and treatment of breast pathology. A review.

Seventy-eight women with breast disease were studied aiming to evaluate the importance of the fine needle aspiration biopsy for its diagnosis and forwarding treatment. Our data showed a high diagnostic accuracy with a low level of false negative results and no false positive. The macroscopic appearance of samples is an important aspect. Clear material prevailed in benign pathology (90%) and the presence of blood was usual in malignant tumors (78.3%).
