Dogs on the scent: can they sniff out cancer?
NCT ID NCT06255041
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether specially trained dogs can identify breast, lung, prostate, or colorectal cancer by sniffing breath samples collected on masks. Over 1,300 people provided breath samples before their regular cancer screening or biopsy. The dogs' results were compared to standard medical tests to see how accurate they were. The goal is to explore if dogs could one day help with early cancer detection.
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 breath test for multiple cancers using trained dogs.
- What could go wrong
- This is an observational study, not a treatment trial. Dogs may not be accurate enough for real-world use, and results may not apply to all populations.
