What is Lung Cancer?

Lung cancer is a malignant tumor that grows in one or both lungs and usually forms in the cells that line the airways and nearby glands. Lung cancer usually develops over a period of years.

Facts & Stats


The American Cancer Society estimates that there will be 220,000 new cases of lung cancer annually in the United States, with about 160,000 people dying each year from the disease.


Lung cancer is often diagnosed in a late stage, thereby associating it with poor prognosis for cancer-free survival.
