A seed-soil predilection appears to constitute a released system of promotion enhancing progression of tumor cell proliferation as a critical step in the metastatic cascade. One might redefine events in terms of promotion of pathways influencing subsequent acquisition of attributes. Permeation and embolic spread via vessels would constitute a realized idealization of events primarily characterized in terms of ongoing changes in phenotype of tumor cells both as genetically unstable cells and as increasingly self-progressive pathways of strictly sequential type.
