Physical activity and cognitive function in breast cancer survivors: a cross-sectional comparative study

Background
Breast cancer is currently the most frequently diagnosed cancer worldwide and the leading cause of cancer-related death among women. Recent studies have emphasized the various challenges survivors encounter post-treatment, including anxiety, sleep disturbances, and depression, all of which significantly affect their quality of life. Despite growing interest in this field, there is limited research examining the association between the levels of physical activity and cognitive function in breast cancer survivors.

Aims
Aims: This study aimed to examine the relationship between physical activity levels, cognitive function, and quality of life in breast cancer survivors. We asked whether physical activity supports cognitive health and enhances post-treatment recovery.

Materials and Methods
A cross-sectional comparative study was conducted with breast cancer survivors (BCS) and age-matched healthy controls (CG). Physical activity was assessed via the International Physical Activity Questionnaire. Quality of life and cognitive function were measured using the EORTC-QLQ-C30 and the Montreal Cognitive Assessment. Group comparisons were analyzed using the Mann-Whitney U test (p < 0.05).
