Lung cancer is the leading cause of cancer death. A number of screening trials have been carried out over the past two decades and have failed to demonstrate a reduction of lung cancer-related mortality. Recent advances in new forms of technology--spiral low-dose CT--have resuscitated interest in screening programs.
Preliminary results are promising but the outstanding question is whether the magnitude of improvement is sufficient to affect a measurable reduction in lung cancer mortality?
