Metastatic breast cancer is a type of breast cancer that has spread from the breast to other parts of the body, such as the bones, lungs, liver, or brain. It is considered to be Stage 4 breast cancer, indicating that the cancer has advanced beyond the breast tissue and lymph nodes. Metastatic breast cancer is not curable, but it can be treated to help manage symptoms and prolong life. Treatment options may include chemotherapy, radiation therapy, hormone therapy, targeted therapy, and surgery. Research in this area focuses on developing better treatment methods, understanding the mechanisms of metastasis, and improving quality of life for patients living with metastatic breast cancer.
