CT Scans Significantly Over-Diagnose Lung Tumors

The Associated Press reports on new findings published in JAMA Internal Medicine that have shown that lung tumors may be over-detected by CT scans. Researchers “used data from the National Lung Screening Trial (NLST), a randomized trial comparing screening using low-dose computed tomography (LDCT) vs chest radiography (CXR) among 53,452 persons at high risk for lung cancer.” Data showed a significant over-diagnoses of lung tumors amongst the LDCT arm, meaning the tumors that were detected were so slow-growing that they did not cause symptoms and were unlikely to ever become deadly. “The findings underscore the need to identify biological markers that would help doctors determine which tumors are harmless and which ones require treatment.”
