Definition of Metastasis

Metastasis is the spread or migration of cancer cells from one part of the body (the organ in which it first appeared) to another. The secondary tumor contains cells that are like those in the original (primary) tumor. For example, breast cancer cells may spread (metastasize) to the lungs and cause the growth of a new tumor. When this happens, the disease is called metastatic breast cancer. (NCI)
