Thai researchers are developing an AI-powered breath test that could make early cancer screening cheaper, faster and more accessible, especially for people in rural areas and community hospitals.
The innovation, developed through cooperation between Chulalongkorn University, King Chulalongkorn Memorial Hospital, MUI Robotics and researchers linked to Mahidol University, uses artificial intelligence to analyse volatile organic compounds, or VOCs, in a person's breath.
Researchers said the technology has shown screening sensitivity of 85% for liver cancer, 97% for pancreatic cancer and 82% for bile duct cancer, offering a new non-invasive option for detecting cancers at an earlier stage.
First, a sensor array detects VOCs in breath.
Second, signal processing converts the signals into digital data.
Third, an AI model analyses the smell pattern, or “smell fingerprint”, to classify disease risk.
