radioactive sugar?

hi has anyone had a petct scan with radioactive sugar injected into them? im freaking out about it, never heard of this before.

any one??? …im really scared that its spread, im thinking that they seen the mri and saw that it was in my lymph node and so they are checking my body for more cancer …all this and haven’t even had my results yet!!! i’m totally freaking out and having panic attacks because of it …did anyone else have mri and pet/ct before there official diagnosis?
