Wow! Thanks for that in-depth response. I
My MRI showed the mental nerve as an active area as well as the floor of my mouth. Tomorrow I have a biopsy of the floor area scheduled to confirm the spread and then I have a video visit with the immunotherapy doctor (Dr Alain Algazi) on December 21.

After that visit I'll post back with their plan or options and I'd be extremely grateful for your help with all that.

And, yes, the inoperable designation came from the panel of doctors after my MRI.

Thanks again for your help. As a Veterinary Technician I have some medical knowledge that both helps and hurts sometimes.
