metastasis
Pronunciation (mĕ-tas′tă-sis, -sēz)
- The shifting of a disease or its local manifestations, from one part of the body to another, as in mumps when the symptoms referable to the parotid gland subside and the testis becomes affected.
- The spread of a disease process from one part of the body to another, as in the appearance of neoplasms in parts of the body remote from the site of the primary tumor; results from dissemination of tumor cells by the lymphatics or blood vessels or by direct extension through serous cavities or subarachnoid or other spaces.
- Transportation of bacteria from one part of the body to another, through the bloodstream (hematogenous metastasis) or through lymph channels (lymphogenous metastasis).
