Lung Cancer Deaths/Population

A cartogram suggests that deaths due to lung cancer were highest in the United States, Europe, and Asia (top). That's because these countries appear much larger than they do compared to a similar map of global population (bottom).

Of the more than a hundred recognized cancers, lung cancer accounted for the most cancer-related deaths in 2002. A major cause was cigarette smoking, but exposure to dust containing asbestos, iron oxides, chromium, and radioactivity also played a part.

Globally, all known cancers accounted for 7,144,549or about 12 percentof the 57 million deaths in 2002.
