<s>[INST] hi, I am a 27 year old male, yesterday I noticed at work my right nipple was a little sore to the touch. Today it has swelled a little more around my areola and I'm getting concerned. I run occasionally but have never had joggers nipple. nor was I bit by anything. I'm afraid it may be inflammatory breast cancer. Please help! [/INST] Hi ! It is not possible to give opinion about a rare possibility. I would suggest you to visit your nearest surgeon, and get yourself examined clinically and investigate yourself if need be. It could be just a simple inflammation due to unnoticed abrasion or an insect bite which has frightened you. Till then you can go for an anti inflammatory drug and possibly an antibiotic on consultation with your family physician. Good luck. </s>
