I know someone who died at the age of 42 fo this disease. She had been complaining to dentists about it, thought she must have an abcess. She was diagnosed too late. She lost half her face, half her jaw bone, had to endure skin grafts, and lost half her toungue. She lived cancer free for about two years and when they found it on check up again it was systemic. She died within the year. Very aggresive, very nasty cancer.
