(May 13, 2008 - Insidermedicine) Welcome to Insidermedicine's If I Knew Then, where we learn from the collective wisdom of clinicians and researchers in medicine.

On a recent trip to Palo Alto, we caught up with Dr. Steven Chang, MD, who is the Director of CyberKnife Radiosurgery at Stanford Hospital & Clinics, and is also an Associate Professor of Neurosurgery at the Stanford University School of Medicine. Dr. Chang’s extensive clinical research studies include the treatment of cerebrovascular disorders, as well as the use of radiosurgery to treat tumors and vascular malformations of the brain and spine.
