Lung cancer is a broad term for different types of cancers that begin in the lungs.
Smoking puts you at greater risk for developing non-small cell lung cancer (NSCLC). This is the most common type of lung cancer. Early diagnosis is key.
While smoking remains the most common cause of lung cancer, you can develop the disease if you smoked very little or never smoked at all. Genetics are becoming an important key to treating these cancers.
Chemotherapy uses drugs that kill cancer cells or stop them from multiplying. Learn more about this treatment.
