Breast cancer survivors who exercise moderately (3 to 5 hours per week) after diagnosis, reduce risk of recurrence by 40% to 50% compared with more sedentary women.

Prostate cancer survivors who engaged in vigorous activity for at least 3 hours per week had a 61% lower risk of death compared with men who engaged in less than 1 hour per week.

Clinical research indicates that physical activity has beneficial effects on overall quality of life for survivors, including body image/self-esteem, emotional well-being, anxiety, fatigue and pain.
