Lung Cancer Screening Study With Low-dose CT Scan and Blood Biomarker

Lung cancer is the number one cancer killer in the USA. Early stage lung cancer is asymptomatic. Most patients with lung cancer are usually symptomatic at diagnosis and already have advanced stage disease. Low dose CT screening (LDCT) for high risk individuals has recently been shown to decrease lung cancer mortality by 20%. However, 4 out of 5 lung cancer deaths are not prevented with LDCT screening alone.
