My husband had a meningioma, discovered incidentally, at age 76. It was not causing symptoms, so he elected active surveillance for about a year. Because the tumor was growing very slowly but the edema surrounding it was growing rather more quickly, he elected to have surgery after a year. He was heavily influenced by the fact it was clear surgery would become necessary, and, as he aged, the surgery impacts would be greater. The surgery was done by Dr. Lanzino at Mayo Rochester. It was a great success. No side effects. Excellent recovery from surgery. He would do it the same way again.
