I don't know if the surgery will be the same so I hope this helps?
I had tongue cancer and I had surgery
I had my tongue and voice box completely removed and reconstructive surgery on the floor of my mouth.
I was told no guarantee it would work (something to do with margins)
Nearly 3 years on and I am still here.
It has been extremely difficult at times however I believe yes worth it as I am still here.
Please feel free to ask me anything if you think it will help
