What Does My MRI Scan Report Indicate?

Question: I have had a MRI done on my brain which shows that I have a growing Acoustic Neuroma size 14x7x5mm.
I have seen two ENT specialists who both take one look at the report and say that having this tumour removed is not recommended.
I am77yrs old and have lived my whole life with very mild cerebral palsy which affects my right side slightly. eg I walk with a slight limp, and have limited use in my right hand. but can hold parcels etc in this hand.
Until a few years ago I lived a full and active life, swimming, walking, climbing. My condition has not stopped me from leading a very normal life, living and travelling to many different countries.
In the MRI report I am seeking to know what the following are: Perinatal ischaemia, Gliotic change, perinatal insult.
After my latest MRI scan which was done a couple of days ago my GP is planning to arrange for me to see
Professor Foote, who is head of Gamma ray surgery at XXXXXXX XXXXXXX hospital in Brisbane.
But will he take one look at the MRI report as the first two specialists did and read about Perinatal ischaemia and gliotic change, and refuse to operate. Why would he do this if my condition has allowed me to live a very normal and useful life for 77 years. I need to have this treatment as I have become very unsteady and need a cane to help me. I have also lost hearing in my right ear. I am also the primary carer for my wife 78 years who has parkinsons, and needs my help at all times.
IF you can explain the words that I have mentioned in this letter it will help when I next see my GP.
Thanks XXXXXXX Chaning-Pearce
