Abstract

This book explores a variety of conceptual and methodological questions about cancer and cancer research: Is cancer one disease, or many? If many, how many exactly? How is cancer classified? What does it mean, exactly, to say that cancer is “genetic,” or “familial”? What exactly are the causes of cancer, and how do scientists come to know about them? When do we have good reason to believe that this or that is a risk factor for cancer? How is cancer a product or byproduct of multilevel evolution? Is cancer research unified? What sort of models, or theories, govern cancer research? This book takes a close look at these philosophical questions, by examining work in disciplines as diverse as cell and molecular biology, epidemiology, clinical medicine, and evolutionary biology.
