Pathology results

I have multiple solid masses in the left axilla, but no breast tumors showed on a mammogram in july. I had a biopsy (Core and FNA) last Friday and just got results. The path report says "The finding of a monotonous appearing lymphoid population may indicate a lymphoproliferative disorder.   They are awaiting results of flow cytometry to make further diagnosis and if that test does not give enough results, then they will do a surgical biopsy. I have researched this a bit and it seems to me that the "monotonous appearing" is indicative of some type of malignancy, although most seem highly treatable.   Am I correct that "monotonous" would indicate some type of malignancy?  Is there any case where "monotonous" can be present without a malignancy?
