INTRODUCTION
Lung cancer remains the most common cause of cancer mortality in the United      remains poor at 23% due to the often advanced stage of disease at the time of diagnosis.1 However, early detection with annual low-dose CT scans can reduce cancer-related mortality by 20%.2 As lung-cancer screening
becomes more prevalent, smaller pulmonary nodules are being detected. However, distinguishing what is       at sub-centimeter sizes. Imaging tests are less accurate and invasive tests are associated with additional costs and possible unnecessary complications. An unanswered question is how aggressively we should pursue lung cancers less
than 1cm in size. To help answer this,

we investigated the characteristics
and outcomes of sub-centimeter lung cancers being detected at the Helen
F. Graham Cancer Center & Research Institute at ChristianaCare. We have also collaborated with the Wistar Institute Cancer Center in developing a peripheral blood test that will detect malignancy in sub-centimeter nodules. This information will help guide the management of small lung cancers.
