Hi Debb, 

I'm sorry to hear that your results have come back showing that you need some treatment. It's understandable that you're feeling nervous and anxious about things. 

There are a number of posts on the forum by people who have experience with this kind of treatment. If you use the search function in the blue bar at the top of the page and use the term "gamma knife" you'll be able to read through them. 

We have some information on our website about gamma knife which you may find helpful and of course if you'd like to chat to someone then our team of nurses are available Monday to Friday 9am to 5pm on 0808 800 4040.
