DIAGNOSIS

TREATMENT

• Surgery to remove part of the lung, or in some cases an entire lung, may be performed. Surgery for some tumors may not be possible because of their size or location.
  
• Chemotherapy (using drugs that kill cancer cells) is commonly used to treat cancer. Chemotherapy drugs are often given by vein.
  
• Targeted therapy (using drugs that target proteins on the surface of lung cancer cells) is a new form of treatment.
  
• Radiation therapy kills cancer cells by using high-energy rays supplied either by an external source aimed at the tumor or by implanting tiny radioactive particles directly in the tumor.
  

Chemotherapy and radiation therapy can have serious side effects, especially because these 2 treatments affect healthy as well as cancerous cells. Typical side effects include nausea, vomiting, hair loss, mouth sores, and fatigue.
