Gamma Knife Surgery

I have friends who are cancer survivors. A number are breast cancer survivors while one is a nose cancer survivor. However, I do not know anyone who has brain cancer but it is good to also know what it is and be aware of the types of treatment there are. Did you know that there's a radiosurgery treatment called Gamma Knife Surgery? A site I found has useful information both for our own knowledge and for sharing with friends and family.
