Welcome @PatrickB
I’m not very far away – in Leicestershire – and have had a different path from you but we have a load of people here who have gone through gamma knife or are going through gamma knife. There’s a very useful story in our AVM101 category.
Sheffield is the major centre in the UK for radiotherapy in this way, so the vast majority of UK radiotherapy patients have been under the care of Sheffield.
Feel free to ask anything you want. I would encourage you to read around the site. Avoid restarting old conversations but anything that’s current, feel free to ask your questions in (or we can move your post to a new topic).
Welcome!
Richard
