<s>[INST] Hi A friend of mine noticed a lump on his chest. Doesn't hurt but is quite noticeable as it protrudes. He noticed it about 3 weeks ago. Any idea what it could be? At the moment, his doctor advised him to have an xray then come back after a month. Please advise. Thank you very much. [/INST] Hi.Thanks for your query.Lump on the chest of the male patient with 3 weeks of history should be seen by a General Surgeon.Clinical examination and ultrasonography with FNAC should give us a final diagnosis and a decision whether to remove it or not. As a thumb-rule, it is better to get rid of any swelling which is not a part of the body for 2 reasons:1. You get rid of the mass by removing it2. You get a confirmed diagnosis by Histo-patho examination. If something serious the early diagnosis helps . </s>
