Tx (for both micro- and macroprolactinomas) is primarily medical
     Dopamine agonists (e.g. bromocriptine and cabergoline*)
          *a new drug that is more effective and has fewer side-effects than bromocriptine
          Medical tx results in
               Normalization of PRL levels
               Significant reduction in tumor size
     Surgery may be required for patients that don't respond to medical therapy
     Radiotherapy may be indicated for aggressive tumors that do not respond to medical and surgical therapy. 
          The response to radiotherapy is generally delayed, and there is a risk of development of panhypopituitarism.
