First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at a new DNA-based test to find thyroid cancer in people with thyroid nodules. Researchers want to see if this test can accurately tell if a nodule is cancer or not, which could help avoid unnecessary surgeries. About 22 adults with thyroid nodules will provide samples after a standard needle biopsy.
