Coming up, Where We Live, Dr. Lisa Sanders joins us to talk about her new book, Every Patient Tells a Story: Medical Mysteries and the Art of Diagnosis.  Dr. Sanders writes the monthly column "Diagnosis" in the New York Times Magazine and is technical advisor for the TV series House, M.D.    We'll talk about those difficult cases where despite everything modern medicine has to offer, patients suffer from illnesses that elude certain diagnosis.  We'll go with Dr. Sanders to the front lines of medicine and inside the diagnostic process, a process that Sanders calls, "the most difficult and most important component of what physicians do."
