Fine needle aspiration in the diagnosis of breast masses: our experience

The authors compare their experience, obtained after 626 examples of fine needle aspiration cytology of the breast, with the results of other departments. The very high specificity of the test is confirmed (absence of false positive). Also false negatives are quite low (6%). Finally, the repeatibility of such a procedure and the low cost suggest inclusion of fine needle aspiration cytology in every diagnostic protocol for mammary cancer.
