The process evolves volatile organic compounds (VOCs), principally alkanes, which are excreted in the breath. VOCs in alveolar breath provided sensitive and specific markers of lung cancer. Breath VOC analysis is a non-invasive test which may potentially detect lung cancer at an early stage and reduce the high mortality of the disease. |
