Early Cancer Detection 1 article

Early Cancer Detection covers biotechnology aimed at finding cancer before symptoms or advanced disease, especially through molecular and blood-based screening. Multi-cancer tests, cell-free DNA signals, tissue-of-origin models, sensitivity, specificity and population validation are central because screening performance depends on both biology and prevalence. The category is distinct from MRD, which looks for disease after treatment, and from diagnostic profiling performed once cancer is already suspected or established.
