The inhibition of tumor growth by tumor mass.

Abstract

Evidence suggests that a tumor behaves, in its pattern of growth, like an integrated organ rather than a collection of independently growing cells. Tumor growth tends to slow progressively as size increases and to undergo compensatory growth after partial resection. Consequently, therapies that reduce tumor mass may tend to accelerate the growth of the remaining tumor and tumor metastases. An approach to therapy based upon a simulated increase in tumor mass may be worthy of consideration.
