Lung Cancer (as cause of Chronic Cough)

Causes <2% cases of Chronic Cough

Normal CXR is very reassuring.  Only need CT if:
  • Smoker >30 pack-years
  • Hx of asbestos exposure
  • Hemoptysis

Screening asymptomatic smokers for lung cancer is different from W/U of “Chronic Cough” (uses low-dose CT).
