Have You Quit Smoking? New Study Has Both Good And Bad News For You
Quitting smoking has benefits for lung cancer risk after even five years, but increased risk persists for at least 25 years after quitting.
Smoking kills 1,300 Americans every day, so quitting is indisputably good for your health, but not an easy feat, with only 15-20% of people who try to quit actually succeeding according to recent reports.
Researchers at Vanderbilt University Medical Center in Tennessee studied almost 9,000 participants, following them for at least 25 years.
During this period, they found 284 lung cancers were diagnosed, of which 93% occurred amongst heavy smokers who had smoked at least one pack of cigarettes a day for 21 or more years.
