Breakthrough breathalyzer test can quickly screen for lung cancer — here’s how it works
- Researchers in Texas unveiled a noninvasive breath test that uses a sensor and AI to detect eight cancer-related biomarkers.
- In a 67-person study, the test correctly identified cancer markers in 90% of cases.
- The test collects breath, analyzes VOCs with a biosensor, then uses AI to match the pattern to known cancer biomarkers.
- UT Dallas professor Shalini Prasad says breath can reveal health signals, though it’s challenging to analyze.
- The team envisions integrating the test in primary care like annual physicals, enabling earlier referrals.
- Cancer screening remains challenging due to CT scan drawbacks and false positives.
- Lung cancer remains the deadliest US cancer, with about 350 daily deaths projected in the study’s context.
- The American Cancer Society highlighted rising 2025 lung cancer diagnoses and deaths, underscoring the need for better screening.
- Researchers emphasize ongoing work to improve the device and test it in real-world medical settings.
- The study’s findings were released by the New York Post in coverage tied to the researchers’ work.
