Men with breast cancer may experience the following symptoms. Sometimes, men with breast cancer do not show any of these symptoms or signs. Or, these symptoms may be caused by a medical condition that is not cancer. If you are concerned about a symptom or sign on this list, please talk with your doctor.

- Any new irregularity (redness, scaliness, puckering) on the skin or nipple, or a discharge from the nipple
