Performance of a multi-cancer early detection test in the randomized controlled NHS-Galleri trial

The NHS-Galleri trial is a randomized controlled study testing a blood-based test for early detection of multiple cancer types as an addition to standard care. The research involved more than 142,000 participants without suspicion of cancer. Secondary endpoint analyses provide insights into the performance of this blood test. The study was published in Nature Medicine in September 2026. The test was added to participants' standard healthcare. The results help understand how effectively a blood test can detect cancer in its early stages.
