Radiation therapy is a method used to kill tumor cells. It tends to work best when used with other methods such as
chemotherapy. It may be used after surgery to kill tumor cells left behind. Sometimes, it’s used to ease problems caused by the tumor.
The types used are:
External Beam Radiation
This type is made by a machine outside the body. Short bursts are aimed at the tumor. It's most often given over many sessions. For some, single doses that are more focused may be better.
The craniospinal type treats the whole brain and spinal cord. It’s used when there’s been a spread to nearby layers or fluid.
