What are the symptoms and signs of male breast cancer?
People with breast cancer may experience one or more of the following symptoms or signs. Symptoms are changes that you can feel in your body. Signs are changes in something measured, like taking your blood pressure or doing a lab test. Together, symptoms and signs can help describe a medical problem. Sometimes, people with breast cancer do not have any of the symptoms and signs described below. Or, the cause of a symptom or sign may be a medical condition that is not cancer.
Talk with your doctor if you have the following signs or symptoms:
A lump that feels like a hard knot or a thickening in the breast or under the arm. If there is a small amount of breast tissue, it may be easier to feel a small lump.
Any new irregularity on the skin or nipple, such as redness, scaliness, puckering, or a discharge from the nipple
If you are concerned about any changes you experience, please talk with your doctor. Your doctor will try to understand what is causing your symptom(s). They may do an exam and order tests to understand the cause of the problem, which is called a diagnosis.
If cancer is diagnosed, relieving symptoms is an important part of cancer care and treatment. Managing symptoms may also be called "palliative and supportive care," which is not the same as hospice care given at the end of life. You can receive palliative and supportive care at any time during cancer treatment. This type of care focuses on managing symptoms and supporting people who face serious illnesses, such as cancer. Learn more in this guide’s section on Coping with Treatment.
Be sure to talk with your health care team about symptoms you experience, including any new symptoms or a change in symptoms.
