Cancer patients often experience a persistent fear of cancer recurrence from the time of diagnosis throughout the survival period. This fear can lead to both physical and psychological dysfunction, disrupting coping abilities. The objective of this article is to delve into the definition, characteristics, related factors, consequences, assessment instruments, nursing care, and management strategies for cancer patients grappling with the fear of cancer recurrence. It was observed that female patients, those of a younger age, individuals with advanced cancer stages, as well as those experiencing psychological dysfunction and social-emotional impairment, were more prone to harboring a fear of cancer recurrence. Elevated levels of this fear correlated with sleep disturbances, poor emotional responses, impairment in physical functioning, and habitual rumination. Nursing management strategies encompassed various approaches, including self-regulation techniques, mindfulness practices, cognitive behavior therapy, and fear mastery training.
