The emergence of solid stress as a potent biomechanical marker of tumour progression.

Cancer is a disease of dysregulated mechanics which alters cell behaviour, compromises tissue structure, and promotes tumour growth and metastasis. In the context of tumour progression, the most widely studied of biomechanical markers is matrix stiffness as tumour tissue is typically stiffer than healthy tissue. However, solid stress has recently been identified as another marker of tumour growth, with findings strongly suggesting that its role in cancer is distinct from that of stiffness. Owing to the relative infancy of the field which draws from diverse disciplines, a comprehensive knowledge of the relationships between solid stress, tumorigenesis, and metastasis is likely to provide new and valuable insights. In this review, we discuss the micro- and macro-scale biomechanical interactions that give rise to solid stresses, and also examine the techniques developed to quantify solid stress within the tumour environment. Moreover, by reviewing the effects of solid stress on tissues, cancer and stromal cells, and signalling pathways, we also detail its mode of action at each level of the cancer cascade.
