Antioxidants, and vitamins what they allow and suggest, dental trays (an appointment with a dental oncologist - is very neccessary), blood work including TSH levels, a prescription for magic mouthwash, possible prescription for Ativan (the mask can be claustrophobic, and they attach it and you to the table). Appointment with a dietician, and if he wants your hubby to have a peg.

also he should have had a scan in between his surgery and treatment, so they should be able to tell you the results, and where they are going to focus the rads.
Hugs!
