Today we'll look at the benefit of CT Scans to decrease lung cancer death rates. This research evaluated almost 8000 smokers in New York who underwent a CT scan of their chest. The scientists looked at this group to two unscreened groups (let's call them USG1 and USG2).
The results showed a significant reduction in lung cancer mortality. They saw a 36% drop from group USG1 and 64% from group USG2.
So basically smokers had a CT screening of their lungs despite not having any other symptoms. This is controversial because hospitals and insurance carriers don't want to pay for a "screening CT scan", but with results like this, particularly in smokers, it does appear to be cheaper in the long run than treating a prolonged course of lung cancer.
