[|Human|] hi, I am 20 years old, male, rock climb frequently and work out. Recently, I noticed this small ball on my front left collar bone that I can move. It can be moved under the bone so that it disappears from sight. It does not really hurt or anything. Can you tell me what it might be?
[|AI|]  Hi, dairy have gone through your question. I can understand your concern. You may be supraclavicular lymph node enlargement or some soft tissue tumor.  Lymph node enlargement may 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. 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.
