Radiation therapy may be used to help treat a brain tumour. Learn how radiation therapy works and what you need to know before your child begins treatment.

Key points

  • Radiation therapy is the use of high-energy X-rays, gamma rays, or particles to destroy tumour cells.
  • Before radiation begins, your child will have a special mask created and require a planning CT scan and possibly an MRI.
  • Radiation is not dangerous for family members or friends; your child is not "radioactive."
  • Side effects may include fatigue, excessive sleepiness, hair loss, nausea or vomiting, and headaches.
