Lung Cancer Screening With Helical Computed Tomography in Older Adult Smokers

Abstract

Concerned smokers and their physicians are contemplating screening for lung cancer with helical computed tomography (CT).^1-4 Having an average 5-year survival of 15%,⁵ lung cancer is often diagnosed at advanced clinical stages when treatment is typically noncurative. Therefore, physicians and their patients have long sought screening methods to detect lung cancer at localized stages, when it can be surgically removed and possibly cured.
