Breast Cancer – Metastatic

Also known as stage IV cancer, metastatic breast cancer is the most advanced stage of this disease and is characterized by spreading to other parts of the body, especially the bones, brain, lungs, and liver. Cancers spread when cells separate from the original tumor and travel to other parts of the body through the bloodstream or lymph nodes, starting a new tumor wherever the cell lands. Metastatic breast cancer accounts for the majority of breast cancer related deaths.
