It is the second most common cancer behind skin cancer in both men and women and is the most common cause of cancer death in men and women smokers. Lung cancer is usually asymptomatic until it has reached an advanced stage and has one of the poorest prognoses of all cancers with a 5-year survival rate on the order of 15%. The effectiveness of current diagnostic and therapeutic interventions is, however, largely dependent on the Stage at which the lung cancer is discovered. Thus, lung cancer is a disease for which screening approaches are very appealing. Screening is performed to detect disease at a stage when cure or control is potentially possible. It presumes that a test or series of tests will identify asymptomatic persons at risk for the disease. Persons with a positive result on screening can be further evaluated to determine whether they actually have the disease. Ideally, once a diagnosis is determined, early intervention should change the course of the disease, resulting in decreased morbidity and mortality. These basic principles of screening for any disease are very germane to lung cancer. Success however, is based upon several basic assumptions. There must be effective treatment at the preclinical, asymptomatic stage that can reduce ...
