Lead time bias is a distortion that arises when earlier detection of a condition, for example through screening, lengthens the interval over which a person is known to have the disease without actually delaying its progression or postponing death. Because survival is conventionally measured from diagnosis, earlier diagnosis can make survival appear longer even if the time of death is unchanged, giving a false impression that earlier detection has improved outcomes. It is a critical consideration when evaluating screening and early-detection technologies, whose apparent survival benefits must be scrutinised to distinguish genuine gains from this artefact. Sound evaluation of such technologies therefore relies on outcomes such as mortality in the whole population, or on designs that account for lead time, rather than on survival from diagnosis alone.
