Accumulating evidence suggests that exercise, long known to be a fundamental part of general health maintenance, may have additional benefits for breast cancer survivors. Observational evidence suggests that women who exercise after breast cancer diagnosis have lower rates of recurrence and death compared with sedentary individuals. A growing number of exercise intervention studies show that increased physical activity after diagnosis leads to improvements in quality of life, fatigue, and body image, amongst other end points, and preliminary work shows that exercise can lead to improvements in biomarkers linked to breast cancer prognosis.
