A Scan a Year for Smokers?

Will a scan a year for smokers keep cancer away (or at least keep it curable)? According to the investigators who are doing ongoing studies of 6,318 smokers in New York City, an annual CT scan of the chest is frequent enough to detect lung cancer at an early stage when it is most curable.

Comment: The value of early annual CT screening for lung cancer is still controversial. Issues include the cost and false positive results that lead to unnecessary procedures such as biopsies and surgery.
