Our Team Approach

Our service is founded upon strong collaboration between the hospital's expert pathologists and excellent surgeons, oncologists, radiologists and radiation oncologists. The pathologists consult regularly with the Bladder Cancer team of surgeons, radiologists, oncologists and other pathology specialists to diagnose benign and neoplastic bladder disease, assess its status, and address issues of appropriate care. The multidisciplinary Genitourinary group meets each Monday at 7am in the Marburg Historic Conference room to discuss specific patient diagnoses and treatment options.
