confused with my PET scan results!

[hunnybear723]

I was diagnosed with Hodgkin's lymphoma in 2008 and just had another follow up PET scan done last week.  The PET scan shows some lymph nodes in the arm pit and pelvic area but the lymph nodes are normal/within normal limits. the nurse said its fine and i shouldn't worry but i am still very concern!!!!  what does this mean? should i be worry? is this a sign of releapse? if its normal, then why is it showing on the PET scan?  Please help! thank you!

>  if its normal, then why is it showing on the PET scan?

perhaps they mean that the nodes are of normal size, but the nodes are 'lighting up' on the PET - which means they are taking in more of the radioactive sugar than would be usual. They take up more of the radioactive sugar (FDG) because the tissue is more active than usual and therefore it is using more glucose fuel.

What is the SUV (Standardized Uptake Value) for the nodes? An SUV can be elevated because of cancer, that's true - but also from an infection which makes the nodes work harder doing their regular job.

I am not sure- but if you are concerned maybe you can ask for a second opinion....

Not to be noisy- but symptoms lead you to get check out for cancer..
