Overdiagnosis as an extreme form of length-time bias. Breast cancer screening as an example

Overdiagnosis is an error of prognosis. Overdiagnosis is not an error of diagnosis. Overdiagnosis is a “true positive” diagnosis. We cannot distinguish between overdiagnosis cancer and non-overdiagnosis cancer. In this presentation the focus is on the vision of overdiagnosis as extreme form of length-time bias, and the research lines which might help in the future to resolve the problem. Please, download the presentation because it is a dynamic one.
