3) In breast carcinoma, accuracy of FNABC is 60%, sensitivity 64.3%, specipicity 88.2%, false positive 40%, false negative 10%.
4) In benign lesions, accuracy of FNABC is 90%, sensitivity 83.3%, specipicity 54.5%, false positive 10% and false negative 60%.
5) Incidence of breast carinoma in the breast nodule is 19.4%, cyst 1.4%.
