This volume provides the most comprehensive and authoritative account of cancer epidemiology currently available. The long-awaited Second Edition has been greatly expanded and contains much new material on cancer biology, molecular epidemiology, preventive strategies and specific types and sites of cancer. It represents a systematic updating and expansion of its predecessor, while retaining a similar organization. No other source contains so much information on risk factors for cancer. New chapters describe the emerging methodology and applications of molecular genetics such as the stages in neoplastic development and molecular epidemiology in cancer prevention. The epidemiologic reviews of risk factors and causal mechanisms for specific types of cancer include new sections on anus, vagina, and vulva. Among the other new sections is a chapter on the principles and applications of cancer prevention. A critical and authoritative review of the complex issues in preventive oncology, this book will be invaluable in planning strategic preventive interventions at the community level, the workplace, the physicians office, or the clinic.
