How do the metastatic cells travel to other sites in the body to metastasize? Blood or lymph systems. Sentinel lymph nodes and blood are ways to possibly monitor the shedding of metastatic cells, but won’t tell you where the end up. A cancer that isn’t shedding metastatic cells is much more treatable than one that is pumping cells into the circulatory system.
