Metastatic breast cancer
(Stage IV)
Metastatic breast cancer—a form of advanced breast cancer also referred to as stage IV breast cancer—is diagnosed when a breast cancer has spread to other parts of the body. If the cancer has spread to the bones, it is called bone metastases. Cancers that have spread to the liver, lungs, or brain are called visceral metastases. Metastatic breast cancer often develops as a recurrence of a previously diagnosed breast cancer. In a small number of cases, metastatic breast cancer is diagnosed when there was no prior history of breast cancer.
A breast cancer tumor that has traveled outside the breast region is still thought of as breast cancer in the new location. For instance, if breast cancer spreads to the brain, the tumor in the brain is considered metastatic breast cancer and not brain cancer.
