Welcome to TheEsquire to the Forums and thank you for making your first post!
Like you, I didn't want to wait 6 months. I wanted my acoustic neuroma treated right away. And when my neurosurgeon told me I needed to wait six months for a second MRI, I sought a second opinion.
The specialists at the Mayo Clinic told me that when the tumor is only 3-4mm, I could afford to wait six months for a second MRI so they could determine the rate of growth. Most acoustic neuromas grow very slowly. Some people can wait ten years or more before any treatment is needed.
With surgery, there are serious risks. If you read these forums, you will see others who have had surgery and have had facial paralysis and other serious results from the surgery.
So, in the neurosurgeon's mind, why is waiting another 6-months not feasible? If you waited another six months, and had a second MRI, and it showed no growth at all, then why would you want to take the risks involved in brain surgery? You might be able to live another 10 or 12 years without facial paralysis or other complications?
You asked for advice on advocating for surgery, and what I have given you is just the opposite -- but it is what the neurosurgeons told me. I did not have good reasons to counter their arguments, so I waited the six months (against my will) and had the second MRI.
My second MRI showed that my acoustic neuroma had no growth. Actually, it shrunk from 4mm to 2mm. Now, my neurosurgeon says there is absolutely no reason for me to take the risks of surgery now, but to continue to monitor it.
So, I just want to tell TheEsquire that often the doctors know what they are doing. I was wrong about demanding that they do my treatment right away. I can't say that your experience will be the same as mine was. But I just wanted to give you something to consider.
I wish you well on your journey!
