title: Corollary to the embolic theory of cancer dissemination.
abstract: The accepted embolic theory of cancer metastasis has hitherto been taught strictly in terms of discrete deposition of tumor tissue away from the primary site. However, since metastasis is a dynamic phenomenon, discrete deposits do not remain static after their formation but grow further and coalesce either with each other or even with the primary tumor. Thus, coalesced deposits are a natural sequel to discrete deposits. Accordingly, the phenomenon of coalescence deserves the status of a corollary to the main theory of embolism.
