In-depth information concerning thyroid problems that may arise as a result of your child's brain tumour diagnosis and/or radiation therapy, and what can be done to manage them.

Key points

  • The thyroid gland is located at the base of the neck and produces “thyroid hormone” which regulates metabolism and energy use by the body.
  • Abnormalities in thyroid function may be associated with brain tumours located near the pituitary gland, or as the result of radiation therapy involving the brain or spine.
  • Thyroid problems may develop months or years after treatment has ended, so thyroid hormone levels will be checked each year.
  • Medications can be used to supplement an underactive thyroid (hypothyroidism) or suppress an overactive thyroid (hyperthyroidism).
  • Radiation involving the thyroid gland may cause the growth of thyroid nodules (lumps) which may be benign or malignant.
