Cancer lies dormant in all of us. Like all living organisms, our bodies produce defective cells every day, from which tumors can develop. But our defense system tracks down these cells and keeps them in check. In Western countries, however, one in four people dies of cancer. This means that these people had a corresponding genetic disposition to develop cancer and/or their immune defenses were unable to protect them. Michael Spitzbart, MD, explains how cancer develops and how we can keep it at bay - with very simple means. His goal is not to treat individual diseases symptomatically, but to optimize health in such a way that no disease can overtake us or that we can defeat it. In this book, he shows which natural defense options are also available for cancer and how we can easily integrate them into our everyday lives.
