Metastatic breast cancer is a type of advanced breast cancer that has spread (metastasized) beyond the breasts. This is the most advanced stage of breast cancer. The symptoms and diagnosis of metastatic breast cancer depend on where the cancer has spread in the body. This will also influence the treatment options, which can be tailored to the person. Metastatic breast cancer can spread to any part of the body, but the following locations are the most common.
