Sir Harpal Kumar explains the Galleri multi-cancer early detection (MCED) test

We routinely screen for just three cancers in the UK,[1] but more than 4 in 5 cancer deaths are caused by cancers without recommended screening programmes.[2] Hear Sir Harpal Kumar, Chief Scientific Officer and President, International at GRAIL, explain the Galleri multi-cancer early detection (MCED) test, which can detect more than 50 types of cancer before symptoms appear[3] – when there may be more treatment options available.[4] Learn more: http://galleri.com http://grail.com Galleri should be used in addition to healthcare provider recommended screening tests. The Galleri test does not detect a signal for all cancers, and not all cancers can be detected in the blood. False-positive and false-negative results do occur. Galleri is a screening test and does not diagnose cancer. Diagnostic testing is needed to confirm cancer. Rx only. See Important Safety Information: https://www.galleri.com/safety-inform... 1.
