What Does Metastasis Mean?

Metastasis is the term used to describe the spread of cancer from its origin to other parts of the body. Breast cancer metastasis occurs when a tumor in your breast tissue sheds some of its cancerous cells, which then find a way out of the breast to other organs. Left untreated, breast cancer that has metastasized can become quite difficult to manage and treat, and some deaths due to breast cancer have been caused by this process. However, while some breast cancer types metastasize more quickly and efficiently than others, early detection and treatment is the best defense.
