    I went for a checkup last week and the doctor wanted a PET scan run

    I had that done and it showed a lymph node lit up. The doctor says that's no concern. I thought anything that "lit up" was showing it has cancer. Is that not how it works? Why would this node be of no concern?

      Neither the CT, MRI, US or the PET are cancer detectors. They are high-tech cameras that produce images. Those images must be interpreted. For instance, your brain and liver light up the PET, as the PET measures only metabolic activity. That could be your entire body, right? "Hyper-metabolic" activity what doctor is looking for, as that "may" indicate cancer, or it may indicate inflammation, injury or the healing process.

      I would say that the level of "SUV" (Standard Uptake Value) of that node was low enough, or the node was remote enough, or small enough to be of no concern. Go to your treatment center's website and look up "imaging" - specifically PET scans. It will give you the basics so that you can keep up with what doctor is saying.

      That's a great description Po18 gives you. I understand your thought process. I was just looking for a clean screen too with no red showing. If it's not red that's probably good. Try not to freak out over the scan, most likely you're moving down the right path right now.

      I had one at the beginning of my treatments, or I should say when I was first diagnosed. I was told vaguely how they work and was operating on the idea that anything red was bad too.
