### input:
I had a breast reduction done for cosmetic reasons and the pathology report showed no abnormality in the breast tissue but said the axillary nodes taken were reactive and had sinus histiocytosis. My surgeon said these are both benign conditions and was not worried at all, but I am wondering what might have caused the nodes to be reactive in the first place and how common a finding this is. Also, does it indicate I need to pursue further testing to figure out what the original cause of the reactivity was? I was due to start my period two days after the surgery, so I m wondering if the nodes could have been reactive because the period was about to start. I have always been very healthy with no other problems. I am 45.

Hi, Dear,Thanks for your query to Chat Doctor. Dear I read your query and reviewed it with context to your query facts. Based on the facts of your query, you seem to suffer from-Reactive Nodes-meaning hyperplasia of the nodes in response to some subacute load of infection-which could be generalized as from Viral/bacterial from recent throat infection even and may not be related to the Breast Pathology. Or this reactivity could be due to the post breast reduction surgery which you had recently. This node reactivity by no means is related to the impending menstrual period. In this scenario-there is no need and hence I don't suggest any further investigation to pursue the cause of the reactivity of these axillary nodes, even though your menses were to start 2 days following the breast reduction surgery. Hope this reply would help you to plan further treatment with your family and specialist doctors there. Welcome for any further query in this regard. Good Day!! Chat Doctor. N.
