metastasis

Pronunciation: (meh-TAS-tuh-sis)

The spread of cancer from one part of the body to another. A tumor formed by cells that have spread is called a “metastatic tumor” or a “metastasis.” The metastatic tumor contains cells that are like those in the original (primary) tumor. The plural form of metastasis is metastases (meh-TAS-tuh-SEEZ).

Definition from: Cancer.gov

Metastasis. In metastasis, cancer cells break away from where they first formed (primary cancer), travel through the blood or lymph system, and form new tumors (metastatic tumors) in other parts of the body. The metastatic tumor is the same type of cancer as the primary tumor. Metástasis. En la metástasis, las células cancerosas se separan del sitio donde se formaron inicialmente (cáncer primario), se desplazan por medio del sistema vascular o linfático, y forman nuevos tumores (tumores metastásicos) en otras partes del cuerpo. El tumor metastásico es el mismo tipo de cáncer que el tumor primario. Date last modified: 2014-11-19Metastatic CancerCáncer metastático
