What is Lung Cancer?
Lung Cancer is cancer that forms in tissues of the lung mostly in the cells lining air passages. Lung cancer is divided into two large groups which represents different types of cells.
Non-small cell lung cancer is the most common type of lung cancer. The most common forms of non-small cell lung cancer are squamous cell cancer and adenocarcinoma. Non-small cell lung cancer is a fast-growing or aggressive cancer that forms in tissues of the lung and can spread to other parts of the body. The cancer cells look small and oval-shaped when looked at under a microscope. It is more common than small cell cancer, occurring in 85% of patients with lung cancer, while small cell only occurs in 15% according to the National Comprehensive Cancer Network. www.nccn.com
Small cell lung cancer is less common than non-small cell lung cancer and looks different when examined under a microscope. In the past, small cell lung cancer was often called oat cell cancer.
Both types of lung cancer can spread to other parts of the body. Lung Cancer is both the most frequently diagnosed cancer in the United States and the most frequent cause of death from cancer. It is often found in people who have smoked, but many people who have never smoked also develop the disease.
Some symptoms of lung cancer include:
Lung cancer treatment depends on several factors, including the type and size of the cancer, its location and your overall health. Surgery, radiation therapy and chemotherapy are the primary tools for treating lung cancer and may be used alone or in combination.

The radiation oncology team is always looking for new ways to treat and cure cancer through studies called clinical trials. Today’s lung cancer radiation therapy treatments are the result of clinical trials completed in the past proving that radiation therapy kills cancer cells and is safe long term. For more information on clinical trials, ask your doctor or visit:
Radiation oncologists are the doctors who oversee the care of each patient undergoing radiation treatment. Other members of the radiation oncology team include radiation therapists, radiation oncology nurses, medical physicists, dosimetrists, social workers and dietitians.
