Key Points

  • Lung cancer screening can help find lung cancer at an early stage when it is easier to treat.
  • At this time, studies have shown that low-dose CT scan is the only lung cancer screening tool that reduces the risk of dying from lung cancer.
  • Lung cancer screening is not right for everyone.

One reason why lung cancer is so serious is that, by the time you have symptoms, it may already have spread and become more difficult to treat. Screening is looking for cancer before you have any symptoms, which can help find cancer at an early stage when it may be easier to treat.

Early detection of lung cancer can save lives for those at high risk and in turn, reduce the lung cancer burden in the United States. Lung cancer screening for those at high risk needs to be part of preventive care strategy to catch more lung cancers early and significantly improve the low survival rates.

To help determine whether or not a screening test is recommended, scientists study screening tests to find those with the fewest risks and most benefits. They look at results over time to see if finding cancer early decreases one's chances of dying from the disease. Data show that screening for lung cancer with low-dose computed tomography (LDCT) reduces the risk of dying from lung cancer in the high-risk population. Other screening tests such as chest X-rays and sputum cytology have not been found to be effective, and are no longer recommended for screening.
