Lung cancer is by far the leading cause of cancer death among both men and women, making up almost 25% of all cancer deaths.12
The survival of patients with lung cancer at 5 years after diagnosis is only 10% to 20% in most countries.13
Screening with low dose computed tomography (CT) for high-risk individuals (current and former heavy smokers) can help diagnose cancer early, when successful treatment is more likely.2
