Oh Patti, I know this is tough and we were all hoping for better news. But, again I'm going to say hang in there, stay positive and strong as much as you can.
The PET scans are an interesting diagnostic tool, however they can show things that aren't actually cancer too. Only a biopsy can definitively diagnosis a cancer tumor.
Hope the doctor's develop the treatment plan and get Ken started soon. At least at that point you will feel more in control, once you are actively fighting the cancer, instead of just looking at it.
Prayers and hugs going your way ~
