Sniffing out cancer: new breath test aims to catch lung cancer early

Summary

This study is testing a new technology called breathprinting, or electronic nose (e-nose), to see if it can detect early-stage lung cancer. Researchers will collect breath samples from 119 people with suspicious lung nodules before they have a biopsy or surgery. The goal is to see if the e-nose can accurately tell who has cancer and who doesn't, and whether it works better for larger tumors.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance
Breathprinting test (e-nose)
What this could lead to
If successful, this could provide a simple, non-invasive breath test to help detect early-stage lung cancer, potentially leading to earlier diagnosis and treatment.
What could go wrong
This is a small, early-stage study (119 participants) testing a new technology. It may not be accurate enough to replace current diagnostic methods, and results may not apply to all types of lung cancer.
