Performance of a multi-cancer early detection test in the randomized controlled NHS-Galleri trial.
Nature medicine·September 22, 2026·PMID 42773209

These results quantify the test's ability to detect cancers and correctly localize the tissue of origin in a large randomized trial, informing clinicians about expected false-positive rates and missed cancers.
