Want to learn more? Here are some of the most commonly asked questions about Lung Cancer answered by Medical Oncologist Dr. Maen Hussein:

Lung cancer isn’t only developed through smoking. How can non-smokers protect themselves from this cancer?
There is no specific practice to protect yourself specifically from non-smoker-related lung cancer. Protecting your health in general — with exercise, avoiding second-hand smoke and committing to healthy diets, as well as avoiding other toxins such as marijuana, can possibly reduce the risk.

What can people who smoke, or have smoked, do to monitor their lung health?
Lung cancer screening is recommended for active smokers or people who quit within 15 years of reaching the age of 55 (and until the age of 79). Patients who meet this criterion should ask their primary care physicians about this low-dose CT chest scan.

What is the difference between lung cancers in smokers vs. non-smokers?
In general, smokers do worse than non-smokers when diagnosed with lung cancer. It could be because smokers may have other illnesses such as heart or lung disease, which makes it harder to be treated. Smoking can also weaken the immune system. There is data that shows when a patient quits smoking after starting treatment for lung cancer, they do better than patients who continue to smoke.
