Tobacco remains the leading preventable cause of cancer death in the U.S., despite a dramatic decline in smoking, a new American Cancer Society report says.

More than 80% of lung cancer deaths are linked to tobacco, data from the inaugural release of the American Heart Association's U.S. Tobacco Atlas states.

That's even though cigarette smoking among adults cratered from 42% in 1965 to just 11% in 2023, researchers said.

Quit rates also have skyrocketed, with a record 62% of smokers trying to drop the habit in 2022, the reports says.
