Male Breast Cancer
Urgent
Male breast cancer is a rare cancer that develops in breast tissue. Although breast cancer is much more common in women, men have breast tissue and can develop breast cancer. A persistent lump is a common presentation, and other possible signs include nipple discharge, nipple or skin changes, dimpling, puckering, redness, or scaling. Finding and evaluating a new breast change promptly can help establish the diagnosis.

When to Seek Medical Attention
Male breast cancer requires prompt medical evaluation for a new breast lump, nipple retraction, nipple discharge, skin changes, or persistent breast or nipple abnormality. Seek assessment for a new or enlarging lump or unexplained changes. Emergency care is generally not required unless there is severe pain, significant bleeding, infection, or another acute complication.

Overview
Male breast cancer is a rare cancer that develops in breast tissue. Although breast cancer is much more common in women, men have breast tissue and can develop breast cancer. A persistent lump is a common presentation, and other possible signs include nipple discharge, nipple or skin changes, dimpling, puckering, redness, or scaling. Finding and evaluating a new breast change promptly can help establish the diagnosis.

Persistent Hoarseness
Causes 1
The exact cause of male breast cancer is not always known. Cancer develops when abnormal breast cells grow and divide uncontrollably. Factors that can alter risk include increased estrogen exposure, inherited genetic changes such as BRCA1 or BRCA2 variants, certain genetic conditions, previous radiation exposure, and conditions that affect hormone balance. Most male breast cancers arise from cells lining the milk ducts.
Hormonal Imbalance
Risk Factors
Risk factors include increasing age, a family history of breast cancer, inherited BRCA1 or BRCA2 variants, Klinefelter syndrome, previous chest radiation, and conditions that increase estrogen exposure. Cirrhosis, heavy alcohol use, obesity, and excess breast tissue may contribute to hormonal changes associated with risk. Men with concerning symptoms or substantial family history should discuss risk with a healthcare professional.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Evaluation usually begins with a clinical breast examination and assessment of the lump or other breast changes. Diagnostic imaging such as mammography or ultrasound may be used to examine the breast and nearby tissues. A biopsy is generally needed to determine whether abnormal tissue is cancerous. If cancer is confirmed, additional tests may assess hormone receptors, HER2 status, lymph nodes, and the extent of disease.
Prevention
Key Prevention Tips
There is no established way to completely prevent male breast cancer
Men can become familiar with their usual breast appearance and seek medical evaluation for a persistent lump, nipple discharge, skin changes, or other new symptoms
People with a strong family history or inherited cancer risk may benefit from genetic counseling and individualized surveillance or screening advice
