The impact of breast cancer on fears of exercise and exercise identity.

<bold>Objectives: </bold>Low exercise adherence is common amongst breast cancer (BC) patients. This study aimed to understand BC patients exercise identity and fears of exercise to identify barriers to exercise participation.<bold>Methods: </bold>Women (18 years plus) currently undergoing, or completed (in remission), chemotherapy for BC, and women (18 years plus) with no cancer history completed three validated questionnaires: Exercise Identity Scale (EI), Exercise Fear Avoidance Scale (EFAS) and Fear of Physical Activity/Exercise Scale - Breast Cancer.<bold>Results: </bold>86 women were included (BC: n = 51 - non-cancer: n = 35). There were no significant differences between groups when comparing overall EI (p = 0.240; d=0.127) and EFAS (p = 0.060; d=0.203) scores. BC reported significantly higher scores on specific questions related to fear during exercise (EFAS 2,3, and 5; p = <0.005). Associations were observed between EI and EFAS questionnaire scores in BC (r = -0.342; p = 0.014), and EI scores and exercise levels in both groups (BC, r = 0.527; p = <0.001; non-cancer, r = 0.639; p = <0.001).<bold>Conclusion: </bold>Results suggest women with BC may have specific concerns and fears of exercise compared to age-matched controls. Education may mitigate fears, increase exercise identity, and promote exercise uptake.<bold>Practical Implications: </bold>Education provided by clinicians at BC diagnosis regarding the benefits and safety of exercise may help mitigate fear and promote exercise identity.
