Cigarette Smoking: Health Risks and How to Quit (PDQ®): Prevention - Patient Information [NCI] - Health Risks of Smoking and Ways to Quit
Quitting smoking improves health in smokers of all ages.
The risk of most health problems from smoking, including cancer and heart and lung disease, can be lowered by stopping smoking. People of all ages can improve their health if they quit smoking. Quitting at a younger age will improve a person's health even more. People who quit smoking cut their risk of lung cancer by 30% to 50% after 10 years compared to people who keep smoking, and they cut their risk of cancer of the mouth or esophagus in half within 5 years after quitting.
