Researchers reported the results of measuring exhaled breath of 14 individuals with bronchogenic carcinoma and 45 control subjects without cancer to develop the screening capability. The authors said that they hypothesized that an "electronic nose" would detect lung cancer on the basis of complex "smellprints" of numerous volatile organic compounds in exhaled breath from individuals with lung cancer as compared with either other non-cancerous lung disease or healthy controls. According to the authors, analysis of results from the "electronic nose" demonstrated its ability to discriminate bet...
