Radiation

Radiation therapy for acromegaly is sometimes used if:

  • All or part of the tumour on the pituitary gland cannot be removed by surgery

  • Growth hormone (GH) levels remain high despite surgery

  • Medical therapy and surgery are not possible or not effective

Radiation therapy uses x-rays to shrink the tumour, or adenoma, and lower the amount of GH produced and released into the bloodstream. You and your doctor will decide if radiation therapy should be part of your treatment plan.

Risks

Radiation therapy has risks. The most common risks associated with radiation therapy are:

  • Permanent loss of pituitary gland function

  • Vision trouble from damage to the optic nerve

  • Changes in memory and cognition
