Hello, my husband was diagnosed in February that he had a 11mm Vestibular Schwannoma. It has grown to 17.6mm at last MRI in June. Since it is currently active and very close to the brain stem he has been advised to have radiosurgery.The side effects look ghastly. I am hoping he won’t be too bad, but would love to be able to speak to anyone who has knowledge of this treatment please?
