All of us have cancer cells in our bodies. But not all of us will develop cancer. This international bestseller, now revised with the latest research, examines what we can do every day to lower our chances of ever developing the illness, and also explains what to do to increase the chances of recovery from it. Dr David Servan-Schreiber was first confronted with cancer when he was working as a medical resident in Pittsburgh. Already a recognised pioneer in neuroscience, by his own admission David had all the arrogant and immortal confidence of a thirty-year-old overachiever. Then he discovered he had cancer of the brain. And his life changed. Servan-Schreiber went on to research alternative medicine and founded and directed a Center of Integrative Medicine at the highly conservative University of Pittsburgh Medical Center. This book is a culmination of his experience in the field of cancer, as a doctor and as a patient. It is his personal story; the story of the cases he has come across, and the medical and scientific story of the disease and its mechanisms. He looks, in particular, at the relation between a body and its cancer; at the immune system; and the roles played by environmental toxins, nutrition, emotions and physical activity in containing cancer. Servan-Schreiber does not dismiss conventional medicine, nor is he anti-pharmaceutical: he empowers the reader with the understanding and the tools to tackle cancer alongside conventional treatments or, better yet, to help avoid cancer altogether.
