Abstract
A method of detecting and diagnosing the probable presence of lung cancer in a mammal, including a human, comprising collecting a measured quantity of alveolar breath from the mammal; analyzing the collected breath for the presence of a marker for lung cancer; determining a first mean alveolar gradient for the marker present in the mammal's breath; comparing the first mean alveolar gradient for the marker present in the mammal's breath to a second mean alveolar gradient for the same marker, found in the breath of a mammal free of lung cancer.
