Could extra stool tests catch bowel cancer earlier and save colonoscopies?
NCT ID NCT07430540
First seen Jun 27, 2026 · Last updated Aug 28, 2026 · Updated 1 time
Summary
This study aims to improve early detection of bowel cancer by having patients provide multiple stool samples (FIT tests) instead of just one. About 1,000 people referred to a hospital in Scotland with possible bowel cancer symptoms will take part. The goal is to see if tracking changes in blood levels over time can better identify who needs a colonoscopy, reducing unnecessary procedures and catching cancers earlier.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- FIT (faecal immunochemical test) stool test
- What this could lead to
- If successful, this could lead to a more accurate and efficient way to detect bowel cancer early, reducing the need for unnecessary colonoscopies and saving healthcare resources.
- What could go wrong
- This is an early implementation study with 1000 participants, not a large-scale trial. The new pathway may not improve detection rates as hoped, and there is a small risk of missed cancers.
