Hi, Claire:
I'm sorry your mum had to go through that. The mental/emotional stress prior to AN surgery can be very difficult for some folks. I trust that, as you mentioned, since your mother now realizes she is basically in good health, she'll be somewhat calmer. I hope so, for your sake and hers. Remind her that she doesn't have cancer and her AN
can be removed. While microsurgery is complicated, some surgeons now remove only enough tumor to spare the facial/cranial nerves and radiate the remaining tumor. I had this procedure and, as you know, it worked out rather well. I certainly couldn't guarantee anyone else's outcome but it seems a safer way to go than trusting micosurgery, alone, to 'get it all' with no post-op complications. Something you and your mum might want to consider, if it's not too late.
By the way, I had a cataract removed eight years ago. A new, synthetic lens replaced it A relatively simple operation (performed in an out-patient eye clinic) and my vision in the affected eye is now 20/20! I'm almost anxious to have the lens in my other eye replaced so I can throw away my glasses for good. Pass that information on to your mum, it might cheer her up a bit.
Try to stay strong, Claire.
Jim
