However, lung cancer screening is not ideal, and issues include a high rate of false-positive results, complications related to diagnostic procedures, radiation-related harms, and patient anxiety. This article discusses the search for biomarkers, exhaled breath analysis, and airway gene-expression profiling, among other topics.</style></abstract><number><style face="normal" font="default" size="100%">4</style></number><volume><style face="normal" font="default" size="100%">13</style></volume></record></records></xml>
