Breath and odor test for early colorectal cancer detection
Part of Cancer clinical trials.
This study tests a new, noninvasive way to detect colorectal cancer and precancerous polyps by analyzing odors in samples (like breath or stool). It aims to make early detection easier and less invasive than a colonoscopy.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be between 18 and 85 years old.
- You may be a patient with colorectal cancer (any stage), or have a precancerous polyp, or be a healthy person with a recent normal colonoscopy.

This study tests whether a simple urine sample can detect colorectal cancer or precancerous polyps. Researchers want to see if this non-invasive test could help identify people at risk before symptoms develop or catch cancer earlier.
This study tests a breath analysis (a sample you give by breathing into a device) to help detect or better understand colorectal cancer. It may help researchers see whether breath results can identify cancer sooner and in people who haven’t started treatment yet.
This study is testing a new breath test that may help detect cancer by looking for unique chemicals in your breath. It could be a non-invasive way to help diagnose or monitor cancer.
This study tests whether a simple breath test can help detect different types of gastrointestinal cancers earlier. If you have been recently diagnosed with one of these cancers or have concerning abdominal symptoms but clear test results, your breath may help teach us how to spot these cancers sooner.
This trial studies a simple breath test to detect cancers of the digestive system, including the esophagus, stomach, liver, pancreas, and colon. It is for people who have been referred by their doctor for tests because they have symptoms that might be caused by cancer.
This study tests a new device that analyzes your breath to help monitor diseases. It may help doctors track conditions early, before treatment begins.
