Breast Cancer

Breast cancer is a malignancy that originates in the cells of the breasts, commonly in the lining of the milk ducts or the lobules that supply the ducts with milk. The condition is predominantly found in women, but can also occur in men. It is characterized by the uncontrolled growth of abnormal cells that can invade surrounding tissues or spread (metastasize) to other parts of the body through the lymphatic system or bloodstream. Risk factors include age, genetic predisposition, lifestyle choices, and hormonal factors.

From a medical standpoint, breast cancer is diagnosed using a variety of procedures, including mammography, ultrasound, MRI, and biopsy. Classification is based on histological appearance, stage of advancement, and the presence of hormone receptors and other markers like HER2. Treatment depends on the type and stage of cancer and may involve surgery, radiation therapy, chemotherapy, hormone therapy, or targeted therapy. The prognosis improves with early detection, which is why regular screening is recommended for early identification and successful management of the disease. Breast cancer awareness campaigns emphasize the importance of understanding symptoms such as lumps, changes in breast shape, dimpling of skin, and unusual discharges from the nipple.
