Psychotherapist Lawrence LeShan has worked with cancer patients for more than thirty-five years and his research has led people with cancer to find new, effective ways to fight for their lives. He has put his findings--full of meaning and purpose--into this revised edition that shows how psychological change, along with medical treatment, mobilizes a compromised immune system for healing. Included is a life-transforming workbook of hands-on exercises designed to help readers evaluate their inner selves and teach them how to get the most out of their immune systems by leading fuller, richer lives.
