The story of the new scientific breakthroughs that have revolutionized the treatment of cancer and other terminal illnesses. The author is a world authority on cancer and its treatment. His quest for a cure began in 1968 when a patient of his with inoperable cancer recovered spontaneously. Had the man's immune system somehow killed the tumour? And if so, can the body rid itself of cancer? From this moment on, Dr Rosenberg seized upon immunotherapy as the most promising path towards a cure for the disease. Most recently he has pioneered gene therapy, a technique in which a patient's own genes are altered in the laboratory and then reintroduced into the bloodstream to attack tumours. So far, his efforts have been profoundly encouraging. The narrative has the power and pace of a thriller - a thriller in search of the keys to life itself.
