"Except in eastern Europe and parts of Africa, mortality among adults has declined in most countries for decades.1 Lower rates of death from infectious diseases were the early driver of this improvement, but there have been subsequent declines in mortality from cardiovascular disease and some cancers.2,3 There have also been important trends in various cancers2 — for example, the rise and subsequent decline in lung-cancer incidence and mortality among men in many high-income countries, a decline in stomach-cancer incidence and mortality as economies develop, and the worldwide increase in breast-cancer incidence."
