MONDAY, Oct. 25, 2021 (HealthDay News) -- Smokers who kick the habit before age 45 can nearly eliminate their excess risk of dying from lung or other cancers, a new study estimates.
It's well-established that after smokers quit, their risk of tobacco-related cancers drops substantially over time.
Researchers said the new findings underscore the power of quitting as early as possible. Among more than 400,000 Americans they followed, smokers died of cancer at three times the rate of nonsmokers. However, smokers who managed to quit by age 45 lowered that excess risk by 87%.
