Q. How is Radiation therapy treatment given?
Radiation therapy can be delivered in two ways. Most common method is External beam Radiation where treatment is done by machines like Linear Accelerators, Tomotherapy and Cycbe-Knife producing high energy x ray. The other method is called as brachytherapy in which tiny millimeter size radioactive sources are placed in natural body cavity like windpipe (Bronchi), foodpipe (esophagus) anal canal, cervix and vagina. These sources can also be placed directly into the tissues during surgery. For eg. In cancers of head and neck, soft tissue tumors (sarcomas).
