It is a situation we all fear and none of us can imagine: a life-threatening diagnosis. But what if the person receiving the diagnosis--young, physically fit, poised for a bright future--is himself a doctor?At thirty-one David biro has just completed his residency and joined his father's successful dermatology practice. Struck with a rare blood disease that eventually necessitates a bone marrow transplant, Biro relates with honesty and courage the story of his most transforming journey. He is forthright about the advantages that his status as a physician may have afforded him; and yet no such advantage can protect him from the anxiety and doubt brought on by his debilitating therapies. The pressures that Biro's wild "one hundred days" brings to bear on his heretofore well-established identity as a caregiver are enormous--as is the power of this riveting story of survival.
