Abstract
Trauma has substantial effects on human health and is recognised as a potential barrier to seeking or receiving cancer care. The evidence that exists regarding the effect of trauma on seeking cancer screening, diagnosis, and treatment and the gaps therein can define this emerging research area and guide the development of interventions intended to improve the cancer care continuum for trauma survivors. This Review summarises current literature on the effects of trauma history on screening, diagnosis, and treatment among adult patients at risk for or diagnosed with cancer. We discuss a complex relationship between trauma history and seeking cancer-related services, the nature of which is influenced by the necessity of care, perceived or measured health status, and potential triggers associated with the similarity of cancer care to the original trauma. Collaborative scientific investigations by multidisciplinary teams are needed to generate further clinical evidence and develop mitigation strategies to provide trauma-informed cancer care for this patient population.
