Traditional cancer screening has always focused on individual organs, but now, multi-cancer early detection (MCED) tests are changing that paradigm. By analyzing multiple biomarkers through a single blood draw, MCED testing can detect signals from a variety of cancers—many of which currently lack effective screening tools. These multi-biomarker approaches not only outperform single-marker tests, but also demonstrate scientific rigor and clinical utility. Still, challenges remain, including false positives and integration with standard screening protocols. Joining Dr. Brian McDonough to explore the rationale for using a multi-biomarker approach to MCED testing is Dr. Marie Wood, Professor of Medicine at the University of Colorado School of Medicine and Medical Director of the Hereditary Cancer Program at the CU Cancer Center.
