Lung Cancer

Lung cancer is one of the most commonly diagnosed cancers. It develops when abnormalities occur in either the lungs or the bronchi (the air tubes leading to the lungs).

People who smoke tend to be at greater risk for the disease, and studies have shown that female smokers may be more likely to develop lung cancer than male smokers. But lung cancer can also occur in people who have never smoked.

Types of Lung Cancer
There are two main types of lung cancer. The type you have depends on which kind of cells the cancer began to grow in. Non-small cell lung cancer is more common than small cell lung cancer, which tends to grow and spread faster than non-small lung cancer.

Because small cell lung cancer tends to grow and spread quickly, the primary treatment is chemotherapy. Treatment for non-small cell lung cancer, on the other hand, usually involves surgery.
