Lung Cancer

Lung cancer is a type of cancer that begins in the lungs. It is most frequently diagnosed in people who smoke or have a history of smoking, but non-smokers can develop lung cancer too. Risk factors include smoking, exposure to secondhand smoke, exposure to certain toxins and having a family history of the disease. Lung cancer is the leading cause of cancer-related deaths in the United States.

There are two main types of lung cancer: non-small cell lung cancer and small cell lung cancer. Subtypes of non-small cell lung cancer, especially adenocarcinomas and squamous cell carcinomas, are generally considered slow-spreading and easier to treat. Small cell lung cancer is the more aggressive of the two main types.

There are many treatments available for lung cancer, include surgery, radiation, chemotherapy, targeted therapy and immunotherapy. Ongoing clinical trials are leading to new and better therapies, too. According to data from the American Cancer Society, death rates from lung cancer have decreased by 51% since 1991 for men and 26% for women since 2002.
