Hi Nevada, 

If you're looking for private healthcare options then I hope these two websites - Private Healthcare and The Private Healthcare Information Network will help. 

I can see there is an article about this treatment on The Brain Tumour Charity's website. I'm not sure if you've come across them before, but if not, it may be worth giving them a call as will be in a better position to advise and give you the information you're seeking at this time.

I hope this helps and you're able to find somewhere that can provide this treatment for you wife.

Best wishes to you both,

Steph, Cancer Chat Moderator
