PET results

My father received PET results that were "mildly positive". He has already been diagnosed with lymphoma from a lump in his neck - I forget the name of it right now. His doctor did not receive the scan itself so he doesn't know if or how he will treat it. My question is: What does mildly positive mean? Is it a staging or a grading? I want to think that it is on the early detection side but I'm uncertain - any suggestions?

Hi.
Did your father undergo treatment for his lymphoma?
A mildly positive result on PET scan would mean there is increased uptake of tracer of the tumor.
PET scan can help in tumor detection, staging, and assessment of tumor response.
It would be best to bring the result of the PET scan to his oncologist for proper evaluation.
Good luck.
