Lead-time bias occurs due to the advance of diagnosis, and length-sampling bias because tumors detected on screening exams are more likely to have slower growth than tumors symptomatically detected. Methods proposed in the literature and simulation were used to assess the impact of these biases. If lead-time and length-sampling biases were not taken into account, the median survival time of screen-detected breast cancer cases may be overestimated by 5 years and the 5-year cumulative survival probability by between 2. 5 to 5 percent units http://hdl.handle.net/10256/15252 Mama -- Càncer Breast -- Cancer Assessing the impact of early detection biases on breast cancer survival of Catalan women
