Radiation Therapy for Metastatic Disease
Radiation therapy damages and kills the cancerous tissue. Kidney tumours are generally not very responsive to radiation therapy. Because of this, the therapy is only recommended to relieve symptoms caused by the primary tumour or metastases that cannot be removed by surgery. Treatment can be given in a single dose of radiation. You could also need to go to the hospital several times for a fractionated course of radiation therapy. In this case you receive one dose of radiation per day.
Radiation therapy for kidney cancer is generally recommended as part of a palliative care approach.
