[/INST] Hello, The hard lump on the chest is probably related to a reactive lymph node. It is benign and is not a matter of concern. I suggest doing an x-ray and a blood test for further evaluation. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr. Dorina Gurabardhi, General & Family Physician </s>
