Breath test shows promise for identifying cancerous lung nodules: study
Summary
A simple breath test could help doctors distinguish between cancerous and non-cancerous lung nodules, potentially speeding up lung cancer diagnosis and reducing the need for invasive procedures. Australian-led research found breath-based methods performed better than standard clinical information alone.
Key Points
- Australian-led research found that a breath test may help distinguish malignant lung nodules from benign ones.
- The study used an electronic nose and gas chromatography-mass spectrometry to analyze volatile compounds in exhaled breath.
- Researchers said the test could help prioritize patients for invasive procedures, but it is not meant to replace biopsies.
- The findings were published in MedComm and highlighted the challenges of biopsying small or hard-to-reach nodules.
