Hopefully they will move quickly based on the path. Shop around but beware of time - if you still have cancer present it can move quickly based on the differentiation, I would want rads as fast as possible - chemo too as they generally go hand in hand. It is a one foot in front of the other proposition. Get through it day to day until you're done. There shouldn't be too many questions to ask other than the type of chemo - how frequently - how many rads - will it be bilateral (with more micro tumors I would hope for a yes - More fall out but better chance of stopping it) and HOW SOON - like NOW?
I'm not being facetious here, you really do want to move ahead quickly - just in case I have stressed that already.

I know you are scared... Just dig down deep and say - I'm gonna do this. Now let's get it over with. You should have a hearing test of its cisplatin they are planning and you will need to see a dentist and have flouride trays made. Hugs and best of luck.
