Simple urine test could spot bladder cancer before it spreads
NCT ID NCT05347342
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study is testing a new urine test to detect bladder cancer early in people at high risk, such as smokers over 50. Researchers will check how accurate the test is and use the data to build a risk calculator. The goal is to offer a non-invasive way to catch the disease sooner.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could lead to a simple, non-invasive urine test to catch bladder cancer early in people at high risk.
- What could go wrong
- This is an early-stage study with 173 participants, so results may not apply to everyone. The test may not be accurate enough for widespread use.
