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.
