When the first edition of this book published in 1994, the psychoimmunology of cancer was still emerging as a topic for serious scientific study. Now, less than ten years later, there is a huge quantity of academic literature about the relationships between psychological variables, the immune system and cancer growth, accompanied by a lively popular interest. In this new edition leading specialists have provided broad critical reviews of the different aspects. Part I, which presents the biological background, will be of particular interest to those with technical knowledge of the relevant laboratory based disciplines. It covers mechanisms mediating the effects of psychological status in the immune system, and anti-cancer mechanisms involving the immune system. Part II is clinically orientated, and accessible to a wide audience. Whether psychotherapeutic interventions can help patients live longer, as well as coping better, is obviously the key question and several contributors consider the clinical evidence for this. A new, speculative chapter on the spiritual context of immunity and cancer has also been added. The psychoimmunology of cancer involves many complex issues, understanding of which remains far from complete. However, the contributors, besides reviewing the current state of knowledge and the implications for cancer patients, offer predictions for the future and ideas about further research.
