I had a node scare at the beginning too. 1.7cm node which turned out to be nothing. But I think it's worth asking for a pet scan. I'm in the uk and the Marsden have never mentioned pet scans to me before but I'm sure they must do them as they are a very good indicator of active cancer. I'll also just add that sickness can also cause emlarged nodes.
Speak to your doctors about it. Also as your seminona you could ask about the use of MRI over ct scanning. I'm going to be asking about that next scan as I had a ct yesterday and they give me the willies!
