Metastasis is a pathogenic agent's spread from an initial or primary site to a different or secondary site within the host's body, yet is typically spoken of as such spread by a cancerous tumor. The newly pathological sites, then, are metastases (mets).
Metastasis can occur when cancer cells break away from the primary tumor, where the cancer began. The cells may then enter the bloodstream or lymph system and travel to the bone marrow. The matrix of the bone marrow secretes cytokines, Fasano says.
