A comprehensive guide to understanding and preventing cancer by addressing its root causes.Outsmarting Cancer reframes one of the most pressing medical challenges of our time: how to prevent cancer. In this timely and accessible book, physician and medical researcher Adam Barsouk, MD, presents a sweeping examination of cancer's true origins--biological, environmental, dietary, infectious, industrial, occupational, and behavioral--and makes a compelling case for why cancer prevention must become a central priority in public and personal health. With personal stories from his clinical practice and the latest research, Dr. Barsouk explains why more people are getting diagnosed with cancer--and at younger ages--than ever before. This book explores a wide range of overlooked and misunderstood risk factors, as well as how inequities in diagnosis, treatment, and prevention disproportionately impact underserved populations. Unlike typical cancer books that focus narrowly on diet or organ-specific disease, Outsmarting Cancer takes a comprehensive, systems-level view, urging readers to look beyond the symptoms and target the root causes. Dr. Barsouk explores the role of genetic predisposition to cancer alongside environmental, lifestyle, and public policy influences that may contribute to developing the disease. With rigorous scientific insight, he offers real-world, evidence-based strategies to reduce cancer risk in practical, meaningful ways. Honest, urgent, and empowering, Outsmarting Cancer challenges readers to rethink how we talk about cancer and how we can reduce its burden before it begins.
