Grail Blood Test Found Seven Times More Cancers Than Standard Tests, Data Show

Management hinted this summer the numbers were substantially better than in early studies.

They are.

Grail shared the results during a meeting of the European Society for Medical Oncology in Berlin on Saturday. The company said that among 23,000 adults over 50 years old, its Galleri test found seven times the number of cancers than were detected by standard screens, such as a mammogram or colonoscopy.

More than half of the cancers found by the blood test were at a stage early enough to possibly cure, the researchers reported. Most of those early cancers were also in places such as the liver, pancreas, or ovary, which don’t even have an available screening test.
