Lung Cancer: Quitting Smoking

Why Quit Smoking?

Smoking remains the leading cause of preventable death and disease in the United States. Smoking causes immediate damage to your body, which can lead to long-term health problems. The only proven strategy to protect yourself from harm is to never smoke, and if you do smoke or use tobacco products, to quit.

It is never too late to quit, even if you have a lung cancer diagnosis. Studies have shown that quitting smoking can increase the efficacy of treatment while decreasing the risk of complications.There is a wide range of immediate benefits associated with quitting; lowered blood pressure, decreased fatigue and shortness of breath, improved immune response as well as improved self-esteem. It can also have positive impacts on mood, sleep, and appetite. Long term benefits include decreased risk of additional tumors, increased survival time, decreased postoperative complications, improved response to chemotherapy and radiation therapy, and improved quality of life. 

There are many resources available to help you quit. We encourage you to talk to your healthcare provider about how they can help you stop smoking.
