The role of nature in cancer patients' lives: a systematic review and qualitative meta-synthesis.

Nature provides patients with unburdened physical and psychic space invested with personal significance. Findings propose nature's role as a "secure base" offering patients a familiar and nurturing context from which new perspectives can emerge and caring connections can be made with themselves, others, the past, and the future. As such, nature supported patients to navigate the clinical and personal consequences of cancer. Comprehensive representation of cancer patients' nature experiences identified patient values and care opportunities embedded in clinical and personal environments, which may be considered for future research and care service development.
