Reduced physical activity is one factor likely to weight gain in women after adjuvant chemotherapy for localized breast cancer. Furthermore, physical activity appropriately could improve many prognostic factors and survival of women after breast cancer. Thus, several large cohort studies of women with breast cancer showed an average mortality reduction of 45% associated with moderate physical activity compared with inactivity. Adapted Physical Activity (APA) could also improve fitness, quality of life, body image, treatment compliance and reduce fatigue.
