Performance and safety of a multi-cancer early detection test: the PATHFINDER 2 study

The PATHFINDER 2 study provides important insights into the safety and performance of a new blood test. This test is designed for the early detection of multiple types of cancer. It is an interventional study that examined its use in a general population. More than 35,000 participants were involved in the research. All participants were aged 50 years or older. The goal was to determine how reliably and safely the test works in practice. The results of this study were published in Nature Medicine on September 22, 2026.
