| metastasis |
1. the transfer of disease from one organ or part to another not directly connected with it. It may be due either to the transfer of pathogenic microorganisms (e.g., tubercle bacilli) or to transfer of cells, as in malignant tumors. The capacity to metastasize is a characteristic of all malignant tumors. 2. pl. metastases. A growth of pathogenic microorganisms or of abnormal cells distant from the site primarily involved by the morbid process.
