my friend s r nipple is swollen and enlarged over the last 4 weeks. He was prescripted with some oral antibioties with no significant improvement. Now, he noticed some clear discharge from the nipple, especially at nights. What can it be? It is a cancer or not?
Hi, thank you for using Chat Doctor. I can understand your concern about your friends' health. If both nipple are affected then general cause like increased prolactin level, while if only one nipple is affected then local causes like infection, injury, cancer can be the cause.  Discharge from male breast is not a normal condition, with swollen and enlarged nipple suggest some sort of infection but as you reported antibiotics did not help, one should get tested the discharge fluid, and should progress further investigation or treatment according to the report of discharged fluid. While you feared worst about cancer, it can not be said certainly without getting biopsy of nipple tissue. Hope this will help you. Regards.
