That's a good list, Alicia

On the surgery,

Ask about the margins on the primary - that will tell if they got all the obvious disease or not. If they are 'wide' that that's good - space between the cancer and healthy tissue. If they were 'close' - they were too close for comfort.

On the lymph nodes, ask about extracapular extension, or if all nodes were enscapsulated.

On the radiotherapy, ask about:

The number of Gy (grays) to the various areas.
The number of sessions
How are missed sessions made up
Music or anti-anxiety drugs during sessions

On the chemo:
If cisplatin or other platinum base therapy is offered, ask about a baseline hearing test.
If cisplatin is offered, if they suggest the 2 or 3 big doses, ask if weekly cisplatin or carboplatin would work just as well.

Ask about a feeding tube.

Best of luck!
