One Blood Test Caught 6.5 Times More Cancers in the Largest US Trial of Its Kind

In the largest interventional multi-cancer early detection trial in North America, 35,878 adults took GRAIL's Galleri blood test alongside standard screening, and cancer detection rose 6.5-fold. Seventy percent of the newly found cancers have no recommended screening at all, and one participant, Franklin Weingarten, 88, is cancer-free today after the test caught his bile duct cancer early.
