Metastasis

Metastasis, or metastatic disease, is the spread of a cancer or other disease from one organ or part of the body to another not directly connected with it. The new occurrences of disease thus generated are referred to as metastases /mə ˈtæs tə siːz/ (sometimes abbreviated "mets"). Metastasis is a Greek word meaning "displacement", from μετά, meta, "next", and στάσις, stasis, "placement".
