New blood test could spot colon cancer before it spreads
NCT ID NCT06342440
First seen Jun 26, 2026 · Last updated Jul 08, 2026 · Updated 3 times
Summary
This study is testing a new blood test called DENEB that looks for tiny molecules (microRNAs) to find colorectal cancer and precancerous polyps early. Researchers will collect blood samples from 2,000 people who are also getting a colonoscopy. The goal is to see if the blood test is accurate and could one day offer a simpler, less invasive way to screen for colorectal cancer.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- DENEB blood test (measures microRNA levels)
- What this could lead to
- If successful, this blood test could offer a simple, non-invasive way to catch colorectal cancer and precancerous polyps early, potentially saving lives through earlier treatment.
- What could go wrong
- This is an early-stage study still recruiting participants. The test may not be accurate enough to replace colonoscopy, and results may not apply to everyone.
