Description of Clinical Expertise

Dr. Geiger's clinical areas of interest lie principally in the treatment of various head and neck and gynecological malignancies as well as base of skull and central nervous system malignancies. He has a strong clinical interest in brachytherapy for gynecological malignancies as well as stereotactic radiotherapy using both GammaKnife and CyberKnife radiosurgery.
