This paper discusses the increasing incidence of early-onset colorectal cancer (EO-CRC), which affects individuals under 50, and its potential to constitute one-third of all CRC cases by 2030. It highlights the critical unknown of how long it takes for EO-CRC to reach metastatic stages, suggesting that this "tumor age" could be significantly shorter than for standard-onset CRC. The text argues tha...
