Metastasis is the spread of cancer from its primary site to other places in the body (e.g., brain, liver).
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.
