Annual scans can catch lung cancer when it is still curable, researchers reported in a study. The findings, which have already ignited a disput among cancer experts, support the argument that yearly computed tomography (CT) scans are worthwhile for smokers and others at high risk, the researchers said.
Although lung cancer kills 95 percent of its victims, a few patients in the study whose disease was caught early by the scans were still alive 10 years later.
