Recent Developments and Recurring Dilemmas in Cancer Screening: Colon, Lung, Thyroid

Screen detection and tumor growth rates. Cancers have different growth rates, which determine their potential to be detected by screening. Tumor A remains microscopic and undetectable by current technology (although more sensitive tests in the future might render it detectable). Tumor Beventually becomes detectable by screening (*), but its growth rate is so slow that it will not
