-
01 Smoking & Secondhand SmokeThe leading cause of lung cancer, driven by tobacco smoke containing over 7,000 toxic chemicals and more than 60 confirmed carcinogens.
-
02 Occupational ExposureProlonged workplace exposure to hazardous industrial materials like asbestos, nickel, and aluminum production significantly increases lung cancer risks.
-
03 Radioactive SubstancesExposure to radioisotopes like uranium is heavily linked to small cell lung cancer, showing a starkly increased incidence rate particularly among smokers.
-
04 Environmental FactorsLong-term high exposure to outdoor air pollution and diesel exhaust containing heavy metals and polycyclic aromatic hydrocarbons (PAHs) raises risks.
-
05 Genetic PredispositionThe vast majority of lung cancers develop from acquired genetic mutations over time, while inherited genetic abnormalities remain exceptionally rare.

Target
Adults aged 54-74 with 30+ pack-years of smoking history.
-
Interval
Every 2 years.
-
Method
Low-Dose Chest CT (LDCT).
- Lung cancer has a high mortality rate and is often diagnosed at an advanced stage.
- Low-Dose Chest CT (LDCT) is standardly performed for the early detection of lung cancer.
- Since July 2019, national screening provides high-risk groups with an LDCT scan every 2 years.
- The eligible program targets high-risk individuals aged 54 to 74 with 30+ pack-years of smoking.
