The FDA is considering how to evaluate multi-cancer early detection (MCED) blood tests, such as GRAIL's Galleri test. These tests analyze blood for signals associated with numerous cancers, aiming to detect diseases earlier than current screening methods, which cover only a fraction of cancer types. While MCED tests are not perfect and may produce false positives, proponents argue they offer valuable information for earlier diagnosis and treatment decisions, a standard that should be applied pragmatically, similar to how other diagnostic tools are assessed.
