Three hundred and fifty women complaining of breast pain symptoms of sufficient severity to interfere with their normal lifestyle were reviewed in a special breast pain clinic over a 5 year period. Seventy-two patients (21%) had spontaneous resolution of breast pain and they required reassurance only before discharge. Of the remaining 278 patients, accurate classification of breast pain syndromes was achieved in 89%, the commonest syndrome being cyclical breast pain which accounted for 54% of the women followed up. The remaining womens' breast pain was classified as trigger zone (14%), continuous (8%), Tietze's disease (5%), spinal root (4%), duct ectasia (4%) and psychological depression (2%). In the remaining 25 patients (9%) the breast pain could not be classified. The experience from this clinic is that a majority of women complaining of severe breast pain symptoms can be accurately classified and appropriate therapy instituted.
