Immunotherapy is an approved treatment for patients with prostate cancer who fail primary treatment, and have been diagnosed with metastatic prostate cancer to only the lymph nodes and bone.  Immunotherapy is accomplished by washing the patients blood through a filter and harvesting the STEM CELLS.  These STEM CELLS are sent to a special regional lab to train them how to recognize and destroy prostate cancer.  The newly trained cells are then placed back into the patient by 3 separate infusions weeks apart.  This therapy has been proven to extend the lives of patients with advanced prostate cancer.
