[|Human|] I have a pea sized hard lump in the center of my armpit.  It seems to be attached to one spot.  I cant feel it on top of the skin.   There is no pain at all when I feel of it and there is no visible sign of it.   I have had type 2 diabetes for seven years controlled by oral meds and have smoked for 30 years.  No history of cancer in family.  Should I be concerned?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may have enlarged axillary lymph node. It can be due to reactive hyperplasia, tuberculosis, lymphoma or metastatic carcinoma.  You should go for fine needle aspiration cytology or biopsy of that lump. It will give you exact diagnosis. Then you should take treatment accordingly.  It has no relation with your diabetes.  Avoid smoking. Consult your doctor and take treatment accordingly. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health.
