The global health challenge of lung carcinoma
In short: Lung cancer remains a leading cause of mortality worldwide, often diagnosed only when treatment options are limited. This video explores the pathophysiology, risk factors, and diagnostic approaches to help turn healthcare consumption into collaboration.
Global mortality from cancer peaked with lung disease in 2022, involving roughly 1.8 million fatalities and 2.5 million fresh diagnoses. The disease occurs when abnormal cells grow uncontrollably in the lungs, primarily manifesting as non-small cell lung cancer (NSCLC), which accounts for about 85% of cases, or small cell lung cancer (SCLC), which is typically more aggressive.
While tobacco smoking is the primary risk factor—responsible for 60–70% of preventable cases—other significant risks include air pollution, radon exposure, and occupational hazards like asbestos. Early detection through screening high-risk individuals is critical, as symptoms such as persistent coughs or chest pain can often be dismissed as minor respiratory issues until they reach advanced stages.
