Lung screening is performed with the goal of finding lung cancer in its early stages, before it causes symptoms. Lung cancer found at earlier stages has more treatment options and better chances of being cured than lung cancer found at later stages.
Lung screening is not for everyone. A large clinical trial including over 50,000 individuals at high risk for lung cancer, led by our own Dr. Denise Aberle , showed lung screening with low dose CT (LDCT) to decrease the rate of lung cancer deaths by 20%. As a result, lung screening is covered by Medicare and private insurance carriers for eligible current and former smokers.
Screening is performed with LDCT of the chest. Low dose CT's use up to 90% less radiation than traditional chest CT's. The radiation received from a low dose chest CT is roughly equivalent to 6 months of natural exposure to radiation from the environment. Because lung screening requires exposure to radiation, it is recommended for those at highest risk of developing lung cancer and who can receive the greatest benefit from it.
Annual screenings improve chances of catching disease early and new guidelines expand opportunities
