Sorta didn't matter where they lived. Lung cancer is the greatest cancer killer worldwide.
And it's the most excruciating, painful way to go too.

Lung cancer is so deadly because it is so hard to cure or keep in remission; over time, most lung cancer patients die from complications, hypoxia and edema are two.
Massive metastasies invade nearby organs as well.
