Low-dose CT lung cancer screening
A chest CT with a lower radiation dose than ordinary CT, used to look for small lung nodules. Since 2019 Korea has included it in national cancer screening for high-risk people aged 54–74 with a smoking history of 30 pack-years or more, once every two years.
Background: Korea ran a pilot in 2017–2018 (13,345 people screened, 69 diagnosed) and included it in national cancer screening from 2019[1]
