Hi!
I just thought I'd share, I had my mask fitting today. It wasn't bad! It was less wet and messy than I assumed it would be. I thought that they would stretch the mask over my face and then I'd be done. But you actually lay there for a little bit while it conforms to your face(maybe 15 mintues). They make some adjustments and mark the mask and then you are done.
They said that the mask will shrink a little bit before treatment. I didn't find it uncomfortable or feel claustrophobic. However, I did ask for medication to take during my treatment and during my CT (you wear the mask for the CT) and MRI. I felt it was better to take it then not and need it during the treatment.
As CC suggested I wouldn't recommend wearing makeup or spend alot time on your hair. The hardest part for me was staying still, I had a hard time relaxing - because I was worried about moving. To have the fitting I had to lay on the table that is part of the Cyberknife - which was kind of neat to see everything ahead of time. The doctor who did the fitting was so nice and made sure I was okay and kept talking to me - which was really nice.
I don't know if this will help anyone but I just thought I would share.
Thanks! Suzanne
