Hey - well everyone here gave you great advice. I know this cancer is a bugger and can pop up in anytime and anywhere, but I would say that usually the nodes are a secondary location. So unless there is a primary hiding somewhere (I'm assuming you go for regular check ups) then chances are it's nothing. Often there is a recurrence in the nodes but usually this is within the first few months to 2 years, so i'd say this far out - not likely unless there's a small tumor somewhere else (unfortunately the fact that you didn't have rads and chemo from the outset does up the odds a bit). I'm not saying it never happens but - not likely - did you have a neck dissection too initially? If so maybe it's a clamp or clip or stitch? I look like Frankenstein on the inside - my dr said - oh yeah I used a lot of clamps!! I can actually feel and see a BIG ONE inside my incision line. I went for a panoramic set of X-rays of my jaw for some dental work I am considering and the girl who took them looked at them and said she wanted to do them again... There was something that looked like scatter all over my left jaw area, I laughed and to her they were staples holding my face together (I kid you not) over 60 - 100 that I could see... Scary weird! anyway hugs and most importantly good luck!
