In this study for determination the efficacy of needle aspiration which is
   done both prospectively and retrospectively , two independent pathologists
   studied blindly the cytologic smear of F.N.A of 75 female patients with
   breast mass (the mean ages were 50.5 years).

          All patients who referred to Kerman Hospitals during 1998-2000 had
   experienced lumpectomy or mastectomy and concommitent surgical slides
   were also reviewed by the same pathologists for definite diagnosis.

          The agreement of two pathologists in the study of F.N.A slides were
   more than 90 percent. The sensitivity and specificity of F.N.A to detect
   malignancy in breast masses were 91 and 78 percent respectively in this
   study. 

          We suggest that F.N.A of female breast mass can be a very sensitive
   and specific procedure in determining their biological behaviors.
