Do not confuse this term with metathesis which is completely unrelated.

Additional Info

Metastatic cancers usually indicate a malignant primary cancer, one that is life-threatening and possibly incurable. The metastic tumor cells are generally like those at the original tumor site and can indicate the original site where the cancer first developed in the body.

Some cancers metastasize easily and others do not. Factors that affect the likelihood of metastasis include the location, type, stage, and size of the original tumor.

Some metastatic cancers can be successfully treated whereas the majority have a very poor prognosis, most metastatic lung and pancreatic cancers, in particular.

SDS Relevance

See malignant. This term is unlikely to appear on a Safety Data Sheet except for a possible description of health effects such as "metastatic bone cancer". Symptoms of exposure will be listed in Section 11 (toxicological information) of the SDS.

The term can also appear on the SDS of drugs used to treat metastatic diseases, of course.
