Role of radiation
Radiation can treat lung tumors that cannot be removed surgically, or that are better treated without surgery. Stereotactic body radiotherapy (SBRT) delivers high-dose, precise radiation over fewer sessions for selected early tumors. Longer courses may be used for locally advanced disease, often with chemotherapy. Radiation can also ease symptoms such as pain, bleeding, or airway blockage when cancer has spread.
Careful planning and image guidance help aim the dose at the tumor while protecting nearby lung, heart, and spinal cord as much as possible.
