Abstract
Humidity profiles of exhaled air of individuals obtained using a sensor to detect water vapor content or temperature versus time of exhalation may exhibit an irregularity indicative of a space-occupying respiratory system lesion. Detection of such irregularities provides an inexpensive and rapid means of pre-screening individuals for lung cancer diagnosis, and is applicable even to individuals with other respiratory disorders such as asthma and COPD.
