A multi-cancer early detection test with high specificity has the potential to revolutionize cancer diagnostics.

by Leo Nissola, MD

The Galleri test detects cancer-related DNA fragments shed into the bloodstream and identifies their source. This technique has the potential to transform the identification of cancer. Early cancer detection is one of the most pressing unmet medical needs.
