A large-scale trial looking into the use of a blood test to see if it can help the NHS detect cancer early has reported a substantial reduction in the most advanced cancers.
The NHS Galleri trial aimed to see if using the Galleri® multi-cancer early detection test alongside existing cancer screening can help to find cancer early. The blood test can detect a ‘signal’ shared by many different types of cancer in a sample of a person’s blood.
