"Q: I smoked for years. Should I get a lung cancer scan? A: Probably not. You may have heard that CT scans can detect lung cancer early. But the tests&amp;amp;#8212;which cost about $300 and usually aren&amp;#x27;t covered by insurance&amp;amp;#8212;haven&amp;#x27;t been proven to lower death rates from the disease. How can earlier detection not help? Some cancers are so aggressive that even finding them early may not save lives. Lung scans also have a high rate of false positives&amp;amp;#8212;meaning, they can misidentify harmless nodules or scars as possible cancers, leading to unnecessary biopsies or surgery. That said, I&amp;#x27;d recommend the scan if you smoked a pack a day for 20 years (or two packs a day for 10 years), in which case nodules are more likely to actually be cancerous and the scan&amp;#x27;s benefits may outweigh its possible downsides. Otherwise, breathe easier. You&amp;#x27;ve already done the most crucial thing to cut your risk: You quit smoking."^^<http://www.w3.org/2001/XMLSchema#string>
