Using a unique framework, Fundamentals of Cancer Epidemiology, Second Edition, helps readers develop an in-depth understanding of the current body of knowledge on cancer—what it is, how it is defined, how it develops in biological and genetic terms, which groups are at highest risk, and what causes it. The new edition has been thoroughly updated to include: New chapters on cancer screening, drugs and cancer, and childhood cancers. Expanded sections on interactions between genetic and environmental risk factors. Recent observations about the biology of normal cells and cancer cells and the implications for determining the etiology of various cancers. New materials on cancer prevention strategies. Expanded discussions about the public health implications of new scientific findings concerning the causes of various cancers. Fundamentals of Cancer Epidemiology, Second Edition, is accompanied by downloadable PowerPoints slides.
