Purpose This study aimed to explore differences in physical activity and fitness between
women with metastatic breast cancer compared to healthy controls and factors associated
with their physical activity levels. Methods Seventy-one women with metastatic breast
cancer, aged (mean (SD)) 57.7 (9.5) and 2.9 (3.1) years after the onset of metastatic
disease, and 71 healthy controls aged 55.0 (9.4) years participated. Of those with metastatic
disease, 27% had bone-only metastases, 35% visceral-only metastases and 38% bone and …

disease onset, and there is little published evidence on their habitual levels of physical
activity. The aim of this study was to investigate differences in physical activity levels and
physical fitness between women with and without metastatic breast cancer. Methods:
Seventy-one women with metastatic breast cancer (METS) aged 57.7±9.5 y and 2.9±3.1 y
after disease onset, and 71 healthy controls (CONTROLS) aged 55.0±9.4 y participated. Of …
