I don't know how large your cancer is but I had a large one about the diameter of a quarter and about two to three quarters high on my hand. It was surgically removed. The doctor had to go pretty deep them make to get it all. I had a long scar there for a while because of the size of the cancer removed. I have not no problems with it returning in two to three years now.
I would suggest you talk to them about surgical removal. If it is very deep into the roof of your mouth that might now be an option.
