Breath Analysis Provides Same Sensitivity, Twice the Specificity of PET Imaging Identifying Early Lung Cancer

Researchers are using breath analysis to detect the presence of lung cancer. Earlier research indicates that this promising noninvasive application offers the same sensitivity of PET scanning, and has nearly twice the specificity of PET for distinguishing patients with benign lung disease from those with early stage cancer.   More...
