The world is in the midst of a medical revolution which is challenging basic assumptions about science and the practice of medicine. Dramatic scientific progress promises better health and longer life, but also creates profound problems. When - if ever - should life and death be manipulated? Is it right that hospitals consume a high proportion of medical funds while vaccinations are withheld from millions in the Third World? Are patients getting the personal care they need from busy doctors? Why, after years of research, is it still not possible wholly to cure diseases such as cancer? How can the mentally ill best be cared for? Focusing on the impact and practice of medical science around the world, this book, which accompanies a BBC2 series, explores how medicine affects our lives. It is based on the human stories and experiences of scientists, doctors, healers and patients. The author's other books include "Becoming a Doctor" and "Childhood".
