AI-Powered blood test could spot colon cancer before it spreads
NCT ID NCT06889883
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to create a blood test that can detect colorectal cancer and advanced polyps early. Researchers will use artificial intelligence to combine molecular markers and personal risk factors. The test will be developed and validated in 510 adults undergoing colonoscopy or surgery. If successful, it could offer a less invasive screening option.
