10 Lung Cancer Causes
2. Second-hand Smoke
Smoking affects everyone around the smoker. Second-hand smoke is another leading cause of lung cancer. After quitting smoking, you need to help everyone else in your life to stop smoking in order to reduce the effects of second-hand smoke. This will also help your friend or family member avoid this form of cancer.
Over 7,000 individuals in the United States die from second-hand fumes. These non-smokers have a high risk of lung cancer due to the harmful habits of their loved ones. Simply living with an individual who smokes can increase your risk of contracting lung cancer by 30%.
