Of course, I am on Google non stop and what I see scares me. Why does everything say greater than 2cm could be lymphoma? So I am a mess. Next Thursday can't come soon enough. Any ideas? I am open to all opinions and stories.
This sounds somewhat similar to what happened to me. This was over 25 years ago, so I may have some of the terminology or sequence mixed up.
I do not necessarily remember the fatigue - I was a freshman in college and was living on my own for the first time. So, I probably would not have recognized fatigue as a symptom if I had it - I would have just thought it was due to studying, going out late, etc.... Anyway, out of the blue I woke up with one or two really swollen lymph nodes in my neck. I felt fine, but I went to the infirmary and the doctor recommended more testing - enough that I flew home (lived about 4.5 hours away by car) and had a specialist look at it. I had the nodes (or one of them) removed for a biopsy. The initial section (cold-section?) looked 'suspicious' and it now seemed like it was either going to be Hodgkin’s or a more severe case of lymphoma. However, the biopsy was sent to the lab for a more definitive test. In the mean time, I was set-up for an immediate Scan (don't remember what type, but that the contrast agent tasted horrible). While I was having the scan, the lab sent word to my parents that the tests came up negative - it was not cancer. This all happened in the space of about 8 days (I ended up missing a week of classes).
My girlfriend's (now wife) father was a practicing ER doctor and the whole time said that it would seem odd to be cancer, since the lymph nodes enlarged seemingly overnight. He was right. I went on to have a few more tests for things like Epstein-Barr, but everything was negative. The Scan revealed that there had been some kind of 'event' but that everything seemed to be draining or going back to normal. I think they just called it 'shoddy-lymph'.
So, like others have said - don't rely on google and don't panic. It may just be some kind of virus/reaction and that is how her immune system is handling it. Perhaps it is just, 'shoddy-lymph'. Rest assured that you are doing the most that you can by having it checked out. Once you get information back, you will know what has to be done, if anything at all.
I know it is trying and you want answers right away. Hang in there and we will keep you in our thoughts and prayers.
