Suzanne,
Sorry it has taken me so long to reply. I had the Novalis unit used on me, they screw a halo to your head and then do a cat scan, then they use the newest MRI and overlap the two so they can get a very accurate measurement and shape of the tumor. After a few hours of planning they bolt the halo (with your head still in it ha ha) to the table and start the radiation. They believed that we should do it with one dose of radiation so they did 13gy which is the maximum that I can ever have, if this thing starts to grow again then it will have to be surgically removed. They went in at 5 different areas of the head all aiming at the tumor. I was pretty dopey from two doses of valium but I believe it was under 1/2 hour for the radiation. Start to finish it was only about 5 hours.
My symptons are vertigo (not always severe), change in taste, some nausia, and because of all of this depression. Not every one has these problems, please do what you think is right. I am constantly second guessing my decision and need to come to terms with it, there is nothing I can do about it now. The best part of all of this is my faith in God, and my relationships have gotten stronger. What ever your decision is it has to be your decision.
Happy Thanksgiving and God Bless you and your family.
