Although quitting smoking is often linked to preventing lung cancer, it can also help you survive lung cancer after being diagnosed. Quitting cigarettes may increase your chance of survival, slow cancer growth, and help prevent complications, according to Kevin Sullivan, MD, Lung Oncologist at Monter Cancer Center, Northwell Health.

If you or someone you know struggles with substance use, help is available. Call SAMHSA’s National Helpline at 1-800-662-HELP (4357) to learn about resources in your area.
