Breath test study for colorectal cancer detection and risk
Part of Cancer, Digestive system clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are 18 years or older
- A doctor referred you because you have symptoms that could be colorectal cancer
- If you already have colorectal cancer confirmed by biopsy, it must be adenocarcinoma (stages I–IV) and you must not have started any CRC treatment yet
- You should not have had prior lower gut surgery that changes anatomy (like hemicolectomy or anterior resection)
- You must not have had chemotherapy, radiotherapy, or immunotherapy for colorectal cancer before
- You should not have taken bowel-prep for a colonoscopy, and you must be able to sign consent

This study is collecting blood samples to improve a test that looks for signs of colorectal cancer in the blood. It may help find cancer earlier or better understand how to detect it.
This research study uses a blood test to look for signs of colorectal cancer in people who have other types of cancer or digestive diseases. The goal is to see if the test can correctly tell the difference between colorectal cancer and other conditions.
This study collects data to improve how colorectal cancer is found and diagnosed. It compares new testing methods (like breath and stool tests) with standard colonoscopy in people with and without cancer or risk factors.
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 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 study tests a simple breath test to detect liver cancer and monitor liver health. It is looking for patients with liver cancer, liver cirrhosis, primary sclerosing cholangitis, or people with normal livers to see if the breath test can help tell the difference.
