What is lung cancer?

Lung cancer starts when cells in the lungs grow out of control. It's the leading cause of cancer death for both men and women. There are two major types: small cell lung cancer and non-small cell lung cancer, with non-small cell being far more common. Smoking is the leading risk factor, though secondhand smoke, radon, and other exposures can also play a role. Finding lung cancer early can improve your treatment options.
