The activation of DNA damage tolerance (DDT) pathways as part of the replication stress response to DNA damage is key for maintaining genome integrity and, as a result, these pathways are closely linked to tumorigenesis. In this Review, Cybulla and Vindigni discuss the many connections between DDT, replication stress and cancer, detail opportunities for clinical biomarker development, and outline therapeutic strategies for targeting these pathways.
