Fifteen years after stopping smoking, a person's cancer risk drops to 50% of the risk associated with continued smoking. A population-based study following almost three million participants in Korea found that quitting smoking at any age helps reduce the cancer risk, and stopping before middle age, especially for lung cancer, reduced the risk substantially.
