C50.A2

Clinical Causes: Genetic mutations that promote uncontrolled cell division Inheritance of genetic predispositions like BRCA1 and BRCA2 gene mutations Hormonal influences, especially prolonged exposure to estrogen and progesterone Environmental factors, such as exposure to carcinogens or radiation Lifestyle factors including excessive alcohol consumption, obesity, and lack of physical activity Previous history of breast cancer or other cancers

Key Symptoms: A lump or thickening in the breast or underarm Change in the size, shape, or appearance of the breast Persistent redness, swelling, or inflammation of the breast skin Unexplained pain in the breast or nipple Nipple changes, such as inversion, discharge, or skin dimpling Flattening or indentation of the breast surface Skin that appears inflamed, warm, or appears to have an orange peel texture (peau d'orange)

Diagnosis Path: Clinical breast examination to assess physical changes Imaging studies such as mammography, ultrasound, and MRI to visualize tumor characteristics Biopsy procedures, including core needle biopsy or surgical biopsy, to confirm malignancy and histological type Laboratory tests to evaluate overall health and rule out metastasis Staging studies like PET scans or CT scans to determine the extent of spread

Treatment Protocols: Surgical removal of the tumor via mastectomy or breast-conserving surgery, depending on the extent of disease Chemotherapy to target cancer cells systemically and reduce tumor size Radiation therapy to eliminate residual cancer cells and reduce recurrence risk Hormonal therapy if the tumor is hormone receptor-positive, using medications like tamoxifen or aromatase inhibitors Targeted therapy aimed at specific genetic mutations or markers associated with the tumor Supportive care to manage side effects and improve quality of life
