My understanding is that to get decent tissue samples, they do have to remove it. The fact that it's unchanged after 3 months is most likely why your doc is going to watch and wait.
Do you have any other lymph node involvement?
I don't have any other Lymph node involvement. Did Dr.s think you had Lymphoma?
I just had CT scans of head, neck and chest looking for enlarged lymph nodes. My mother has CLL, which increases my risk for lymphoma, my father has a multinodular goiter, so do I along with a solid nodule on my thyroid, so that increases my risk as well. My CT scans are clean, I just go back in July for another ultrasound of my thyroid to watch for nodule growth.
I will look into other causes of spleen enlargement for you and see if I can't help!
Have the drs. run a full CBC on you?
