Real quick update: Just got an email from the cancer center radiology department reminding me that I have a PET scan due on the 26th (Wednesday) (a scan from 'the base of the skull to the top of the thighs). It's a ''reminder' of an appointment nobody told me about in the first place.
Made me grin.
Now the cancer center treats me like a queen every time I go down there, but someone needs to work on communication skills.

First, the largest lesions I have are found above 'the base of the skull' (maxillary sinus, lower jaw, back of the head) and in my thighs. Though I do have the one in my left arm and ribs. Therefore, a PET scan that ignores the area where the lesions are might be, er, not as useful as it needs to be. I discussed this earlier with my doctor and he had to change the orders for my last PET scan.
Second, we won't know whether my blood has 'cooked' sufficiently (is ready for infusion) until Tuesday at the earliest, so while a PET scan might be a good idea on Wednesday, it is by no means assured. They don't want to do any further testing until they know it's a go.
At least, that's what I was told.
So, is someone in a bigger hurry than I thought?
Ah, well. Things seem to be going well, yes?
