You can reduce your risk of NSCLC if you quit smoking, but your risk will still be higher than if you had never smoked. If you’ve already been diagnosed with NSCLC in its earlier stages, quitting may help delay the time before your cancer progresses.
Cigarettes and other tobacco-containing products directly expose the lungs to at least 70 harmful chemicals. These chemicals can
While our body can sometimes protect itself from this damage, it gets harder to manage over time. Eventually, the damaged cells begin to grow rapidly and form a mass called a tumor or lesion.

Smoke from other people’s cigarettes, known as secondhand smoke, also causes non-small cell lung cancer. Breathing in second-hand smoke can be just as dangerous as smoking yourself.
According to the CDC, exposure to smoke causes
Research also shows that people with NSCLC exposed to secondhand smoke have worse outcomes, including reduced survival rates.
Yes, quitting smoking will improve your outlook for non-small cell lung cancer. It’s never too late to quit. Even if you quit after smoking for a long time, there are still health benefits.
Even after a lung cancer diagnosis, research shows that quitting can help people live longer. a
The outlook of NSCLC is better when the cancer is detected before it spreads outside of your lungs (localized). Nearly
It’s important to understand that this is just an estimate. Some people with lung cancer survive much longer than 5 years. In addition, advances in treatments, including targeted therapies and immunotherapies, will continue to improve these rates.
If you smoke, recent research found that quitting has been shown to cut your risk of lung cancer by half after 10 years compared to if you continue to smoke.
The best way to lower your risk of NSCLC is to avoid smoking and second-hand smoke. Quitting isn’t easy, but there are resources available, such as:
- nicotine replacement therapies (patches, gums, and inhalers) which deliver nicotine to your body in a safer form than smoking and help you curb cravings
- prescription drugs such as Chantix or Zyban
- smoking support groups
Through clinical trials, researchers are studying new ways to help smokers quit.
To avoid secondhand smoke, don’t allow people to smoke in your house or car, and ask smokers not to smoke anywhere around you. If you’re able to, try to dine in restaurants and live in housing with a smoke-free policy.
Smoking tobacco products like cigarettes is the number-one risk factor for non-small cell lung cancer, the most common type of lung cancer. Smoking can also cause cancer just about everywhere in the body, including the throat, esophagus, stomach, voice box (larynx), kidney, liver, and pancreas.
It’s never too late to quit smoking. Quitting can drastically cut your risk of lung cancer. After 10 years, your risk of lung cancer is about half that of a person who is still smoking. Even if you still get NSCLC, your chances of surviving the diagnosis may be higher if you quit smoking sooner rather than later.
If you need help or advice about quitting or are concerned about your risk of NSCLC, talk with your doctor.
