hematogenous spread
Blood-carried disease transmission
Hematogenous spread is the dissemination of disease—typically cancer or infection—through the bloodstream.
Cancer cells or pathogens enter blood vessels and travel to distant organs, establishing new sites of disease: The tumor showed hematogenous spread to the liver and lungs.
The term appears primarily in medical contexts, distinguishing blood-borne transmission from spread through lymph nodes or direct tissue invasion.
