Thanks Paul,
I have copies of PET/CT on disc along with the image viewer program. Very impressive to zoom and rotate around your own neck. lol

Depending on the facility, sometimes I get them for free and sometimes a nominal fee.

As to minimum of 50 gY to kill SCC, that makes perfect sense why 5300 dosage was painted across the entire left side as a "mop up" meaning to KILL any stray or small, undetected cancers.

I feel very confident they killed any cancer in the HNC area. The thing still worrisome but not making me lose sleep or create any anxiety is what the lungs show this time on the upcoming scans. I have a couple undiagnosed spots that after much flapping about remain a bit of a mystery.

Since the induction chemo was very(near complete) effective in disintegrating all visible tumors and the spots in the lungs remained the logic goes it is likely something else. I see the logic but rather have direct rather than some deductive projection of what that is.

Other than that I really feel confident the C is dead but need a couple years under the belt to celebrate.
