Lung cancer screening rates: Data from the lung cancer screening registry.

Since 2013, the United States Preventive Services Task Force (USPSTF) recommended annual screening for lung cancer with low-dose computed tomography (LDCT) for those aged 55-80 years for those who have smoked at least 30 pack years who currently smoke or have quit within the past 15 years.
