This study aimed to investigate the current status of fall risk perception among this population in China, identify its latent profiles and associated factors, and establish a theoretical basis for targeted nursing interventions.</p> <p>Methods</p><p>Convenience sampling was conducted.

A total of 534 cancer survivors undergoing radiotherapy/chemotherapy were recruited from a tertiary hospital in Zibo City between June and September 2025. The study employed a general information questionnaire, the Fall Risk Perception Scale, the Social Support Rating Scale, the Health Literacy Management Scale, and the Self-Efficacy for Managing Chronic Disease Scale. Latent profile analysis (LPA) was employed to identify heterogeneous subgroups based on perceived fall risk, and logistic regression analysis was subsequently used to examine factors associated with subgroup membership.</p> <p>Results</p><p>Among the 534 enrolled cancer survivors, LPA classified perceived fall risk into three distinct categories: the Low-level Perceptually Deficient Group (22.85%), the Medium-level Condition-dependent Group (49.25%), and the High-level Self-awareness Group (27.90%).
