Overdiagnosis: epidemiologic concepts and estimation

다국어 초록 (Multilingual Abstract)

Overdiagnosis of thyroid cancer was propounded regarding the rapidly increasing incidence in South Korea. Overdiagnosis is defined as 'the detection of cancers that would never have been found were it not for the screening test', and may be an extreme form of lead bias due to indolent cancers, as is inevitable when con-ducting a cancer screening programme. Because it is solely an epidemiological concept, it can be estimated in-directly by phenomena such as a lack of compensatory drop in post-screening periods, or discrepancies be-tween incidence and mortality. The erstwhile trials for quantifying the overdiagnosis in screening mammogra-phy were reviewed in order to secure the data needed to establish its prevalence in South Korea.
