Jon,
You can find a lot of answers by searching this OCF site. There is a 'search function' located at the bottom of the pages. If you search for say 'staging' it will take you to that topic.

If your doctors say that you will need to spend a week in the hospital then is it correct they plan to use surgery to first remove the BOT tumor (a glossectomy procedure) and probably a neck dissection to remove affect lymph nodes followed by chemo/rad using concurrent Cisplatin with TomoTherapy?

TomoTherapy is an excellent modern IGRT-IMRT system and assuming good treatment planning should deliver as good an outcome as technologically available.

Tomo does seem to be a bit easier to tolerate, but this varies significantly based on individual response and treatment planning. Concurrent Chemo can add more complications.

With all that said, Tomo or not, It is not likely that you will be able to work all the way through this (even a limited schedule).

I was fine the first month or so, but the last week of treatment and for two weeks after, working was out of the picture. I was sick the last few day of treatment then totally exhausted for about two weeks. And... I had it easy.

So, hope for the best, but plan for the norm and have some friends and/or family lined up to help you get through this.
