Why would I want to have a lung cancer screening CT?

If you are at risk of lung cancer, you may want to have low-dose CT scan that can help detect lung cancer at its earliest and most curable stage.  The best hope for curing lung cancer is finding it as early as possible.  The Early Lung Cancer Action Program (ELCAP research showed that annual CT screening can find 85% of lung cancers in their earliest, most curable stage (Lancet 1999; 354:99-105). A CT scan can detect tiny spots on your lungs (called ‘nodules’) that may indicate lung cancer in this early stage (New England Journal of Medicine 2006; 355: 1763-1771).  The ELCAP research results together with the National Lung Screening Trial (NLST) (New England Journal of Medicine 2011; 365:395-409) results led to the current recommended program of clinical screening.
