Peeling back the onion: addressing nuances of CT screening for lung cancer

Authors: Frank C. Detterbeck

Abstract

At first glance, screening for lung cancer is straightforward. You can find lung cancer at an early stage with a CT scan, so if you do a lot of CT scans you will save a lot of lives. However, the devil is in the details. One of the problems is that a chest CT detects nodules in many patients; deciding when a nodule is just background noise or warrants closer attention is an important component of the screening process. Nuances of how to do this are still being developed.
