Hi, I had the floor of my mouth removed because of Cancer. They should have your aunt in for tests very quickly to be sure it has not spread to her jaw bone. If not , this is a very good thing. My lining was replaced with a flap from my arm. They took a vein and tissue ane went in thru the side of my neck to do flap. This worked very well for me, the floor of my mouth feel more natural than since all of this started. I have no problems eating or talking except I do get tired because of an artifical bone in my jaw.If they do this , they may leave it bare and do flap later, in 10 days new flesh grew on the floor of my mouth, it covered the bone that was sticking up and rubbing my tongue raw.I was suprised at the growth myself. Even if they do surgery they may still want the radiation.Hope this moves quickly for her after such a long delay.
