Purpose
This study aimed to examine the level of fear of cancer recurrence (FCR) among adult breast cancer survivors and to identify factors influencing it. Methods: This cross-sectional study included 104 adult breast cancer survivors who were no longer receiving active treatment. Data were collected through self-report questionnaires addressing FCR, depression, anxiety, distress, fatigue, coping with cancer, social support, subjective health status, subjective quality of life, demographic characteristics, and disease-related characteristics. Surveys were administered both face-to-face and online between March and September 2024. Data analysis was conducted using descriptive statistics, frequencies, the independent t-test, one-way analysis of variance, Pearson’s correlation, and multiple regression. Results: The mean total FCR score was 78.83±25.71 (range, 0–168), reflecting a moderate level. Among participants, 22.1% scored above the cutoff for depression, 34.6% for mild anxiety, and 27.9% for severe distress. More than 70% of participants reported fatigue. Levels of coping with cancer, social support, subjective health status, and subjective quality of life were moderate or higher. Anxiety (β=.56, p<.001), fatigue (≤34) (β=.18, p=.019), and subjective quality of life (β=–.18, p=.022) significantly influenced FCR. Conclusion: Ongoing assessments and tailored interventions are essential to address FCR and to promote psychological well-being in breast cancer survivors following completion of active treatment.
