Multi-cancer screening tests

Topic

Multi-cancer screening tests, also known as multi-cancer early detection (MCED) tests, are advanced diagnostic tools designed to detect signals from multiple types of cancer simultaneously from a single biological sample, typically a blood draw (liquid biopsy). These tests work by identifying tumor-derived biomarkers, such as cell-free DNA (cfDNA) or specific proteins, in the bloodstream before clinical symptoms appear. They represent a major paradigm shift in oncology, aiming to complement traditional single-cancer screening methods and improve early detection rates.
