My tongue cancer was caused by HPV16. My recommended treatment is chemo therapy and 35 radiation treatments. I had my first chemo treatment yesterday. I had my radiation mask made covering my head down to shoulders. This was the worst thing that's happened to me since being diagnosed with tongue cancer. I have claustrophobia and I started freaking out. Near the end of the mask run through I started trying to get the mask and mouthpiece out and calling for help. Finally that was over only to be told I had to do this one more time. I explained about my fear to the nurse who basically said nothing can be done just do it. Since my treatments will probably start in two weeks I have made requests for a sedating drug such as valium. I was flatly turned down and said it's only 5 minutes deal with it. I can tell you after that 1st day (yesterday) I was physically shaking and could barely walk. Unfortunately this was the one day I did not come with my husband. I am dreading my next radiation treatment. Did anyone out there have similar experiences and if so what did you do?
