OMG! I am so sorry, but from expirience I can tell you first hand that Children's Memorial is a very good hospital. I was diagnosed with a brain tumor at age 8 and had surgery done at the hospital with Dr. Tomita. I am now 25 and doing wonderful with 2 beautiful girls. I had an Astrocytoma in my Crebellum with grew and attched itself to my brainstem. My tumor was non-cancerousr, it is usually non-cancerous in kids. I have had about 20 MRI's in my lifetime so far. Can you find out your nephew's nerosurgeon? I know if it's Dr. Tomita he will take real good care of your nephew.
I see my mother Nite0wl71 responded, Im the DD. PM my mother and talk with her, she knows exactly what your going through. She went through the same thing at the same exact hospital.
