Try to get in touch with a neurosurgeon who has expertise in doing the type of surgery she would need. Apart from this there’s not much you can do at the moment but try to stay calm and reassuring. If there’s understanding of the nature of the problem and what needs to be done as far as intervention, try not to google this stuff - it won’t be predictive of her individual outcome and it would freak anyone out. Stay informed on the subject if you guys feel like you need a second opinion. I hope she has is responsive to the agent used on the mass when you follow-up in February, and that her symptoms improve. Brain surgery certainly is not fun but there is life after.
