Metastatic breast cancer (also called stage IV or advanced breast cancer) is breast cancer that has spread beyond the breast to other organs in the body (most often the bones, lungs, liver or brain). In the U.S., most women with metastatic cancer develop it when the cancer returns at some point after their initial breast cancer diagnosis and treatment.
Although metastatic breast cancer is not curable, it can be treated. And, as treatment continues to improve, so does survival. Today, some people may live many years with metastatic breast cancer. For more information on support for you and your family click here.
