They may honestly not know very much about it at all Alan - the head radiologist at my local hospital did not, it was one of his assistants who said he had heard of it and suggested I find out about it - the rest was left to me.  There is only one hospital in London that does the treatment and it costs around £13,000.  If you google Nanoknife online you can read about it and maybe print the information out for your consultant.

Just wanted to say that the Professor who does the procedure is really helpful and easy to talk to. If your local hospital put your latest scan on a disc for you, you can send it to the Professor and he will let you know if it is possible to ablate but dont leave it long because it is reaching maximum size for the procedure.  Although it is done alongside chemotherapy, I really dont know about the embolisation so thats something to check too. I am pretty sure there wouldnt be a charge for his opinion and at least you would know if it was an option.  It is a really simple procedure to go through - both to gain his knowledge/opinion and for the ablation itself (about 16hrs in hospital and minimum pain which subsides within a couple of days). 

Whichever path you decide to follow, I really hope that your wife responds to the treatment and keeps well. I understand what an awful path this is to go down and see my own dear supportive husband going through it all with me, so know what you are going through and how helpless you must feel.  Please come to chat whenever needed Alan x
