Hi David. Christine is on the money here, I won't repeat her good advice.

Both my PET/CTs were of my head down to my thighs. I didn't think they did PETs of just the head. And if they were looking at your chest and abdomen why do a PET of your head? The radioactive glucose goes right through you, so I would imagine they would scan the whole body? Maybe others can suggest what happened there.

The PET that showed my tonsil tumour and lymph nodes showed up like a Christmas tree. A blind bat wouldn't have missed them. And while they were at it I know they had a good look at something on my spleen, but concluded it was benign.

An ENT will sort you out. Hope its nothing serious. Good luck with the Seminoma.
