Breath and blood may reveal hidden cancer early
NCT ID NCT06346054
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to see if certain chemicals (oncometabolites) in a person's breath and blood can spot early-stage gastro-esophageal cancer. Researchers will compare samples from 1,000 people, including those with cancer, those with Barrett's esophagus (a precancerous condition), and healthy volunteers. If successful, this could lead to a simple, non-invasive screening test for early detection.
