Hi June,
Are you seeing a CLL expert doctor? And is that doctor confident that you have CLL?
If no to those questions, you can get a free 2nd opinion from an expert here: https://cllsociety.org/programs-and-support/exp...
Biopsies or node excisions can be used by expert doctors and pathologists if there is an unclear diagnosis (possible MZL, FL etc.) but if clearly CLL and no hint of a Richter's Transformation - then biopsy would probably not provide any useful information or help guide treatment choices.
