Definitions for "Metastatic cancer"
Cancerous cells that spread from their original location to other parts of the body.
cancer which has spread from the original site to one or more locations within the body
A second cancer that forms in the body as a result of an original (primary) tumor is called a metastatic cancer. It is caused when cells break away from the primary tumor and form another tumor at another site in the body. These secondary tumors are called metastases. Metastatic tumors can become fatal if they disrupt the function of vital organs.
