Blood test could replace needle biopsies for cancer diagnosis
NCT ID NCT03019471
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing whether a blood test can find tumor DNA in people with cancer. If successful, it could lead to a less invasive way to diagnose cancer compared to current methods like tissue biopsies. The study will enroll 40 adults with newly diagnosed breast, colorectal, lung, or brain cancer.
