<s>[INST] Im a 25 yr old male, 55, 150 lbs and have a small lump above my nipple on my right breast. It is about pea sized. It doesnt hurt at all and there is no rash or irritation around it. I would still like to know what it is though and if it should be be checked out. Should this be a concern? [/INST] Hi, thank you for quarry. As you mentioned you said you have a lump in chest which does hurt you. The most chances it's a lipoma, but clinical examination is important to rule out lump because lump site, size,shape, consistancy, reducibility,compressibility and fix to underlying structure or not is important. Lipoma usually not painful, rubbery in consistency freely mobile not connected to underlying tissues.no need to worry about it, if size increased pain or it ml become tense or tender than consult your General Surgeon. Hope the answer will help you in making decision. </s>
