Using a preprogrammed electronic nose, which detects different profiles of volatile organic compounds (VOCs) in exhaled breath, researchers from the University of Latvia examined breath samples from 475 subjects, including 252 patients with lung cancer, 223 patients with different lung conditions and healthy volunteers, 265 smokers and 210 non-smokers.
