What Does Thyroglobulins In Lymph Nodes Mean? Cancer?

I am schedule to have my TT on this coming Tues. May 28th. Things are happening very quickly I was just diagnoised w/Papilliary Carcinoma 3 wks. ago (from a biospy). Then they found Thyrogolbulins in my left lympy nodes, does that mean possible cancer was detected in my lymph nodes or is it just a precautionary measure that they want to remove them during the surgery--not really sure what my Dr stated (my mind is still a little cloudy)? Any suggestions, or recommendations on how to deal w/this surgery and the after effects would be greatly appreciated. My faith sustains me...I just like to prepare for the worst, but expect the best. Thx in advance.
