Men with breast cancer may experience the following symptoms. Sometimes, men with breast cancer do not show any of these signs or symptoms when diagnosed. Many times, breast signs or symptoms can be caused by a medical condition that is not cancer.

The signs and symptoms that should be discussed with a doctor include:

  • A lump that feels like a hard knot or a thickening in the breast or under the arm. Because men generally have small amounts of breast tissue, it is easier to feel small lumps.

  • Any new irregularity on the skin or nipple, such as redness, scaliness, puckering, or a discharge from the nipple

If you are concerned about one or more symptoms or signs on this list, please talk with your doctor. Your doctor will ask how long and how often you’ve been experiencing the symptom(s), in addition to other questions. This is to help find out the cause of the problem, called a diagnosis.

If cancer is diagnosed, relieving symptoms is an important part of cancer care and treatment. This may also be called symptom management, supportive care, or palliative care. Be sure to talk with your health care team about symptoms you experience, including any new symptoms or a change in symptoms.
