I had a clear PET scan over a year ago, my doctor says I don't need another yet. How often do most of you with lymph node/stage IV get tested?

I have a sore throat, sinus drainage, and am very short of breath (unusual for me). I got a chest x-ray and it showed one lung not the same shape as the other.

Don't you think I should get a PET? Or am I just a big baby and worry to easily?



Swollen node, Diagnosed 04/05/10. Stage IV BOT SQCCA, 1 Lymph Node, Radiation and Erbitux, 5 weeks of Ethyol to protect Salivary Glands,no PEG. 10/20/10 PET clear.

I want to make sure other people know about this disease and HPV.
