Carcinogenesis is not a solitary process driven by isolated tumor cells; it is fundamentally shaped by the tumor microenvironment (TME), a complex mixture of various cell types, along with their biophysical and biochemical intricacies. Fibroblasts are essential components of the system that keeps tissues in a state of balance. Yet, even before a tumor manifests, pro-tumorigenic fibroblasts, in close adjacency, can provide the favorable 'terrain' for the cancer 'embryo,' and are designated cancer-associated fibroblasts (CAFs). In reaction to intrinsic and extrinsic stressors, CAFs orchestrate the restructuring of the TME, thus promoting metastasis, therapeutic resistance, dormancy, and reactivation via the secretion of cellular and acellular components. This review provides a summary of recent breakthroughs in CAF-mediated cancer progression, emphasizing the variability and adaptability of fibroblasts.

While metastasis, a heterogeneous and dynamic process driving many cancer deaths, is still a challenging clinical target, our comprehension and treatment approaches are in a state of evolution. Acquisition of a series of traits is critical for metastasis, enabling dispersal, cyclical dormancy, and colonization of distant organs. These events' success is attributed to clonal selection, the dynamic nature of metastatic cell transitions to distinct states, and their capacity to modify the immune system for their own purposes. This document examines the core principles of metastasis, and highlights promising opportunities for creating more effective therapies against metastatic cancer.
