Fine needle aspiration is the least invasive method for biopsy of the breast but it is often unsuccessful due to the difficulty of retrieving sufficient tissue through a small needle. When a diagnosis cannot be made, a more invasive biopsy method is necessary. Needle modification (i.e. develop a small needle with a unique tip or insert) has been requested by our client, which would maximize the tissue obtained to increase the diagnostic yield of this very valuable procedure.
