1. <cell biology, oncology> 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 (for example, tubercle bacilli) or to transfer of cells, as in malignant tumours. The capacity to metastasize is a characteristic of all malignant tumours.
Origin: Gr. Stasis = stand, stoppage
