People over 65 who are current or former heavy smokers may benefit from low-dose CT scans of the lungs to detect cancer, according to researchers from the National Cancer Institute.
Some experts have hesitated to recommend this type of lung cancer test because it has a high rate of false positives, ABC news reports. A positive test requires invasive follow-up tests to determine if the person has cancer.
Medicare is debating whether to pay for the scans, which cost $100 to $400, the article notes. A decision is expected in November.
