Hi!
Why you had your lymph node removed? What were the breast scan results? Did you have lymph node biopsy before it was removed?
Lymphocytes proliferation is a term that can be used for a rare disease know as Autoimmune Lymphoproliferative Syndrome and is manifested in early childhood. In general meaning, lymphocyte proliferation is used to describe a process of rapidly reproducing lymphocytes, so that there are many lymphocytes available which can recognize and fight the invading antigens.
Best wishes!
