Swollen lymph nodes above left clavicle

[cardsfans]

My 8 year old daughter went to the doc on Monday and we discovered that she has enlarged nodes on the left side just above her clavicle.  I'm currently waiting (not so patiently) for the doc to call with appointment for Ped Onc Hemo specialist but I'm freaking out.  She has lost about 3 lbs since Monday.  Her nodes are really tender to the touch.  She has swelling in the nodes in her neck, above clavicle and now in the groin area.  She tested positive for mono in Sept of 07.  Her nodes swelled then too, but not above the clavicle.  I'm really scared that this is something serious...should I be?

My 13 year old daughter noticed a lump abover her left clavicle in July. In Aug I had her pediatrician look at it and after reviewing any other causes (illnesses/injury) and checking for other swollenn lymph nodes (there were none), she sent us for lab work.  All was fine, although I was a little concerned that her Immature Granulocytes No was high .04 (range 0.00-0.03) and her Immature Granulocytes was 0.5 (range 0.0-0.5) which is on the higher end. Her sed rate was on the high end of her range as well 17 w/ a range (1-20) with no obvious illness. The lymph node was measured in Aug at 1.0cm by the pediatrician and did not seem to grow over the weeks we watched it.  In October, we had an xray -all was fine. The lymph node at this point did not seem to be growing but was not going away - it is non painful most of the time, occasionaly hard but for the most part, just semi firmish.  My daughter then had an ultrasound and the lymph node was measured at 2.6 with another enlarged lymph node next to it. We met with a surgeon knowing the known lymph node was coming out, but was informed he wants to grab the other one as well.  I realize for children, odds are that she is/ will be fine but I would like an opinion from someone who does not know my daughter or myself and therefore would not feel bad laying what the chances of this being a lymphoma.  thank you!!

I have swelling in neck area above clavicle.  This swelling has spread to back area of neck also. What is this? I do not feel pain and it is soft.

Hi.
Are there other symptoms aside from the ones you mentioned?
Most of the time, enlargement or swelling of the lymph nodes are caused by infection.  Respiratory tract infection (both acute and chronic) can cause such enlargement or swelling.  Other conditions that can cause enlargement include lymphomas, leukemias, or carcinomas (although not common in children).
A weight loss of 3 lbs in a matter of days is significant.  This warrants further examinations.
Are there any laboratory examinations done like a complete blood count and chest x-ray?
