Swollen lymph nodes for a year, enlarged thyroid no medications. tests all normal, haven't had cbc in a year tho. discussing biopsy, should i?

Biopsy: I would strongly suggest a biopsy especially if the lymph nodes are painless. Among the differential diagnosi is lymphoma. An excisional biopsy is the standard of care to diagnosed lymphoma

Swollen nodes: If swollen nodes are a concern, you can usually have something less invasive than an open biopsy. You can have a Fine Needle Aspiration biopsy also called FNA. The FNA can be used to get cultures and also to exclude lymphoma and other cancers. When suspicion for a lymphoproliferative is high, an open biopsy can be performed. An Ultrasound is a noninvasive test that can also be helpful.
