Hello and welcome to the head and neck group. We have had a few members here with mandible tumors in the past. If they are still checking in then perhaps they will offer up advice.
Myself I had a mandible replacement using a section of fibula bone and flap material to rebuild the gum. A bit of a process but overall recovery and result was far better than any cancer treatment I had prior. So there seems to always be solution for what ails us.
Six cancers and you are still relatively young. I am at a loss for words. Are all of these cancers related?
