The incidence of early-onset forms of many cancers (defined as cancers diagnosed in individuals <50 years of age) has increased in a number of countries over the past several decades. The underlying reasons for this apparent increase probably include greater use of screening programmes, but also changing patterns in early-life exposures. In this Review, the authors describe the emerging global increase in the incidence of early-onset cancers and suggest changes that might address this situation.
