'This book gives plenty of examples of ad hominem attacks, intimidation, slander, threats of litigation, deception, dishonesty, lies and other violations of good scientific practice. For some years I kept a folder labeled Dishonesty in breast cancer screening on top of my filing cabinet, storing articles and letters to the editor that contained statements I knew were dishonest. Eventually I gave up on the idea of writing a paper about this collection, as the number of examples quickly exceeded what could be contained in a single article.' From the Introduction The most effective way to decrease women's risk of becoming a breast cancer patient is to avoid attending screening. Mammography screening is one of the greatest controversies in healthcare, and the extent to which some scientists have sacrificed sound scientific principles in order to arrive at politically acceptable results in their research is extraordinary. In contrast, neutral observers increasingly find that the benefit has been much oversold and that the harms are much greater than previously believed.
This groundbreaking book takes an evidence-based, critical look at the scientific disputes and the information provided to women by governments and cancer charities. It also explains why mammography screening is unlikely to be effective today. All health professionals and members of the public will find these revelations disturbingly illuminating. It will radically transform the way healthcare policy makers view mammography screening in the future. 'If Peter Gotzsche did not exist, there would be a need to invent him ...It may still take time for the limitations and harms of screening to be properly acknowledged and for women to be enabled to make adequately informed decisions. When this happens, it will be almost entirely due to the intellectual rigour and determination of Peter Gotzsche.' From the Foreword by Iona Heath, President, RCGP 'If you care about breast cancer, and we all should, you must read this book. Breast cancer is complex and we cannot afford to rely on the popular media, or on information from marketing campaigns from those who are invested in screening. We need to question and to understand. The story that Peter tells matters very much.'
