Hi Cave,
The only problem I experienced with the mask was near the end of my treatments when I had developed a pretty good case of mucositis. I was afraid of choking on the mucous and arranged a hand signal if I needed the mask removed immediately. The staff at Mass General were great about getting the mask off as quickly as possible once my daily dose of radiation was delivered.
Good luck with your treatments. - Sheldon
