The search for the links between diet, nutritional and metabolic factors and cancer aetiology is an area of research, which over the past two decades has attracted increasing attention both from a scientific and a public health point of view. In this context, the Europe Against Cancer Program has supported the European Prospective Investigation into Cancer and Nutrition (EPIC), a study involving about half a million volunteers in 10 European countries. This book, derived from the European Conference on Nutrition and Cancer (IARC, Lyon 2001, with the support by the Directorate General for Public Health and Consumer Protection of the EU), gives an update of recent scientific developments in the field. It examines the relationship between nutrition and cancer with a multidisciplinary and multifactorial approach encompassing nutritional research, endocrinology, carcinogenesis, molecular biology and genetics.
