Peter, a retired police officer, had no concerns about his health when he signed up for the NHS-Galleri trial and was able to walk for miles week after week. The NHS-Galleri trial is a research study in England that is evaluating whether annual screening with the Galleri multi-cancer early detection (MCED) blood test can help the NHS to detect cancer early when used alongside existing cancer screening programs. Watch Peter’s story of how he was diagnosed with Stage III lung cancer following a Cancer Signal Detected result from the Galleri test. Although treatment left him tired, Peter’s overall health is now back to normal and he is back supporting his beloved soccer team.

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. Based on a clinical study of people ages 50 to 79 around 1% are expected to receive a Cancer Signal Detected result, which includes a predicted Cancer Signal Origin. After diagnostic evaluation, around 62% of these people are expected to have a confirmed cancer diagnosis. The overall sensitivity in participants with lung cancer in a clinical study was 74.8% (21.9% for stage I, 79.5% stage II, 90.7% stage III, 95.2% stage IV). Rx only.
