Environmental Carcinogenesis as a Stochastic Evolutionary Failure of Senescence-Control Systems.
A new theoretical framework explains how environmental cancer risk depends on both mutations and cells' ability to prevent their own uncontrolled growth, refining prevention targets.
This review proposes a probabilistic evolutionary framework for environmental carcinogenesis in which tumor initiation depends not only on carcinogen-induced mutations but critically on the stochastic ability of rare cells to evade senescence-mediated growth arrest. The framework integrates aging, immune surveillance, DNA repair capacity, and tissue-specific microenvironments as modulators of senescence escape probability, potentially refining mechanistic cancer risk models and identifying prevention targets.

Why it surfaced
Integrative conceptual review (Cells) connecting senescence biology to environmental carcinogenesis within a stochastic evolutionary framework, bridging aging biology, tumor suppression, and carcinogen exposure to propose refined mechanistic models for cancer risk and prevention.
