im a 24 year old male, healthy and in shape. resently noticed lumps under my nipples. my left is allot more swollen then the right and is rather hard like a stiff rubber tube. there is slight pain and it is a bit warmer then the surrounding area. I am not able to see a doctor due to working overseas for long periods of time. Any ideas besides cancer? We have antibiotics here if it might be an infection but without the ability to do blood work its hard to come to any conclusion.
