v. (Pathology) transfer of malignant or disease-spreading cells from one part of the body to another through the bloodstream (also metastasise)

For the musical composition, see Metastasis (Xenakis composition).Metastasis (Greek: displacement, μετά=next + στάσις=placement, plural: metastases), sometimes abbreviated mets, is the spread of a disease from one organ or part to another non-contiguous organ or part. Only malignant tumor cells and infections have the capacity to metastasize.Cancer cells can "break away" from a primary tumor, penetrate into lymphatic and blood vessels, circulate through the bloodstream, and grow in a distant focus (metastasize) in normal tissues elsewhere in the body. Metastasis is considered a hallmark of malignancy. All tumors can metastasize albeit to varying degrees, barring a few exceptions (eg. Glioma and Basal cell carcinoma never metastasize).
