New Device Uses Breath Analysis for Early Lung Cancer Detection

Chinese scientists have developed a portable device that detects lung cancer by analyzing isoprene levels in exhaled breath.

Researchers from Zhejiang University have created nanoscale sensors that can detect isoprene levels as low as 2 parts per billion in human breath.
The device distinguishes between healthy individuals and lung cancer patients based on isoprene concentration, with cancer patients showing levels below 40 parts per billion.
This breakthrough offers a non-invasive, low-cost method for early lung cancer screening, potentially improving survival rates.
Initial tests involved 13 participants and demonstrated the device's ability to consistently differentiate between cancerous and non-cancerous breath samples.
Further research is needed to fully understand the relationship between isoprene levels and lung cancer and to refine the technology for commercial use.
