A new blood test can detect over 50 cancers, potentially transforming patient outcomes through earlier diagnosis. The Galleri test identified cancer in 61.6% of cases where a "cancer signal" was detected in the blood, according to the Pathfinder 2 trial. It also accurately ruled out cancer in 99.6% of cases and identified the affected organ 92% of the time. The test, developed by Grail, is being trialled by the NHS and could be used annually for individuals aged 50 and over, though some experts urge caution and further research into its impact on mortality rates.
