NEW YORK, Feb 28: A calculation based on results from a large lung cancer screening trial projects that 12,000 deaths a year among the highest-risk smokers and ex-smokers in the US could be avoided with a national screening program. The National Lung Screening Trial, published in 2010, found 20 per cent fewer deaths from lung cancer in a group of people at highest risk for the disease when they were screened annually with CT scans, a form of high-resolution X-ray that can spot suspicious lung nodules.
