Could a breath test spot lung cancer return?
NCT ID NCT06707519
First seen Apr 25, 2026 · Last updated Jun 22, 2026 · Updated 14 times
Summary
This study is testing whether DNA from blood, sputum, lung fluid, and breath can be used to find genetic changes in non-small cell lung cancer. Researchers will collect samples from 210 patients before and after surgery, then follow them for 24 months to see if these tests can detect cancer recurrence. The main goal is to see if it's practical to collect and use these samples, not yet to prove they work as a diagnostic tool.
