| metastatic cancer | definition: secondary cancer that has spread from one part of the body (primary site) to another (secondary site). It occurs when cells from the primary tumor break away and travel through the lymph system or bloodstream to another site and begin to multiply there producing metastases. Metastatic cancer can be discovered before the primary cancer. On a few occasions the primary site is never found, a condition known as unknown primary. Metastatic cancers are more difficult to treat than primary cancers.

Tiene lugar cuando las células del tumor primario se extienden desde el lugar originario y viajan a través del sistema linfático a otros lugares, formando otros tumores. El tumor metastásico se puede descubrir antes que el tumor primario. En muy pocas ocasiones el lugar original nunca se encuentra, lo que se conoce como cáncer de origen desconocido.
