World Cancer Report: Cancer Research for Cancer Prevention is a multidisciplinary publication, with leading international scientists as authors and reviewers. More than 60 different chapters describe multiple aspects of cancer prevention and the research that underpins prevention, focusing on research activity during the past 5 years. Starting with the latest trends in cancer incidence and mortality worldwide, this publication provides wide-ranging insights into cancer prevention based on the known causes of cancer, factors that determine how cancer develops, and the behaviour of different tumour types, and presents a broad scope of interventions to reduce the cancer burden from a global perspective, including addressing inequalities that affect cancer prevention.
