[|Human|] My son is 19 and under alot of stress, he woke up this morning to find a lump under his armpit, his doctors office is closed today and I will be following this up tomorrow with his doctor, there has been alot of tragedy in our family lately, and I am very concerned on what this might be, he has used the same anti-persperant for years.
[|AI|]  Hi, dear. I have gone through your question. I can understand your concern. You may have some enlarged axillary lymph node or soft tissue tumor like lipoma. Enlarged lymph node may be due to reactive lymphoid hyperplasia or due to tuberculosis.  So you should go for fine needle aspiration cytology. Then you should take treatment according to your diagnosis. 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.
