In this Oct. 23, 2009 photo, Dr. James Wang, center, meets with a patient, left, and third-year Tufts medical student Khalida Itriyeva, right, in his office in Springfield, Mass. After he was sued for allegedly failing to quickly diagnose an appendicitis, Dr. Wang began practice "defensive medicine" -- ordering extra tests, scans, consultations and even hospitalizations to inoculate himself against future lawsuits.
