Genesis : people become patients with high blood pressure -- We change the rules : how numbers get changed to give you diabetes, high cholesterol, and osteoporosis -- We are able to see more : how scans give you gallstones, damaged knee cartilage, bulging discs, abdominal aortic aneurysms, and blood clots -- We look harder for prostate cancer : how screening made it clear that overdiagnosis exists in cancer -- We look harder for other cancers -- We look harder for breast cancer -- We stumble onto incidentalomas that might be cancer -- We look harder for everything else : how screening gives you (and your baby) another set of problems -- We confuse DNA with disease : how genetic testing will give you almost anything -- Get the facts -- Get the system -- Get the big picture -- Conclusion : pursuing health with less diagnosis
