Breath of life: new test could sniff out gut cancers before they spread
NCT ID NCT07714538
First seen Jul 20, 2026 · Last updated Jul 24, 2026 · Updated 3 times
Summary
This study is testing a simple breath test to help detect gastrointestinal cancers—including cancers of the esophagus, stomach, pancreas, liver, and bowel—at an earlier stage. The test measures tiny molecules in exhaled breath that may be linked to these cancers. Participants provide a breath sample before a scheduled hospital procedure, and researchers check whether the test can reliably tell who has cancer and who does not.
