This is a great question Sandralea58,

I completed treatment for a locally advanced Head & Neck cancer in March. About 60 days out. I am having PET scan anxiety coming up 6/1. I feel like I will be told there is still some inflammation and my $100K scan (exaggeration) inconclusive and to rinse and repeat in 4 months. I'm not sure why I have this stuck in my head....perhaps a skeptic in my old age (57).
Your PET scan response was exactly what I am anticipating. Hence I've been on a mission to take everything anti inflammatory I can get my hands on. Including trying not eat anything possibly irritating to my throat although with spring arriving, its hard to avoid all the fruits.
I am curious, like you, of how many people had clear PET Scans at their first scan? If there is such a thing. Also, how often post treatment are we told to rinse and repeat and do another? I ask myself if all this x-ray's good for us if the results are inconclusive anyway.
I would love any feedback on this topic. Thank you.
