Since 2007, John Muir Health’s Clinical Research Center has been participating in a large-scale research project alongside dozens of other hospitals around the world as part of the International Early Lung Cancer Action Program (I-ELCAP) and has screened 250 patients to date. The study quantifies the benefits of low dose CT scans for early lung cancer detection in high-risk patients – current and former heavy smokers ages 55 to 80.
