Grail's Galleri Fails To Reduce Late-Stage Cancers
7.9
Grail’s Galleri blood test failed to show a 20% reduction in stage 3–4 cancer diagnoses among 140,000 Britons over three years, a result that sent Grail’s stock tumbling about 50% last week. The author recounts a personal September 2023 positive Galleri result that led to a May 2024 tonsil biopsy and July 2024 surgery, and warns hospital incentives slow diagnostic adoption.
