C50.129

Clinical Causes: Genetic predisposition, including mutations in the BRCA1 and BRCA2 genes Hormonal imbalances leading to increased exposure to estrogen or other hormones Radiation exposure to the chest area A history of certain benign breast conditions Environmental factors and lifestyle choices, such as alcohol consumption and smoking Age – risk increases with advancing age Obesity, which can influence hormone levels Family history of breast cancer or other genetic cancers

Key Symptoms: A lump or mass in the central part of the male breast Changes in the size, shape, or appearance of the nipple or surrounding skin Persistent pain or discomfort in the breast area Nipple retraction or inversion Nipple discharge, which may be clear, bloody, or another color Skin changes such as dimpling or redness over the breast Swelling or a lump in the underarm area, due to lymph node involvement

Diagnosis Path: Diagnosis of this breast cancer typically involves several steps to confirm the presence and extent of the disease. These often include: - **Clinical breast examination:** A healthcare provider assesses for unusual lumps or skin changes. - **Imaging tests:** Mammograms specifically tailored for men, ultrasound, and MRI scans help visualize abnormalities. - **Biopsy:** A sample of tissue from the suspicious area is collected and examined under a microscope to confirm malignancy and determine the specific type of cancer. - **Additional tests:** Blood tests and scans such as CT or PET scans may be performed to check whether the cancer has spread to other parts of the body.

Treatment Protocols: Treatment for malignant neoplasm of the central male breast generally involves a multidisciplinary approach and depends on the stage and specific characteristics of the tumor. Common options include: - **Surgery:** Often involves removal of the tumor, which may range from a lumpectomy to mastectomy. - **Radiation therapy:** Used post-surgery to eliminate remaining cancer cells and reduce recurrence risk. - **Chemotherapy:** Uses drugs to destroy cancer cells and may be administered before or after surgery. - **Hormonal therapy:** For cancers that are hormone receptor-positive, medications can block hormonal effects to inhibit tumor growth. - **Targeted therapy:** Drugs designed to target specific molecules involved in tumor growth. - **Immunotherapy:** Emerging treatments that help the immune system recognize and fight cancer cells. Following treatment, regular follow-up appointments, imaging, and examinations are crucial for monitoring and early detection of potential recurrence.
