Can small cell lung cancer be prevented?

By far the best ways to prevent small cell lung cancer are to quit smoking and reduce your exposure to second-hand smoke. Ninety percent of lung cancer cases have been linked to tobacco smoke, and people who live with smokers but do not smoke themselves are 20 to 30 percent more likely to have lung cancer. Eliminating exposure to other environmental risk factors, such as radon and asbestos, will also reduce your risk of small cell lung cancer.
