Hi and welcome to OCF Missy.
As you can see by my signature it appears that your husband is going to have much the same operation I had. Mine was also SCC floor of the mouth. Can someone here help with those numbers in Missy's post?
It will be a battle but your husband is lucky to have you as a caregiver. Do not hesitate to ask whatever questions you may have as there are no silly ones. As you can see I have also had to ask for help in my post after all this time!
Good Luck..Gabriele
