Exercise to survive

Physical activity reduces the risk of breast cancer recurrence and mortality, says breast cancer surgeon Carolyn M. Kaelin, MD, MPH.

Stretching can improve range of motion, flexibility and posture; strength training can fight osteoporosis and sarcopenia (i.e., muscle deterioration) that result from chemotherapy and aerobic therapy helps limit the weight gain that often occurs during chemotherapy.

"Both chemotherapy and surgery have profound impacts on the body," says Kaelin. Since treatments and their effects vary, each patient should receive a customized program for health and fitness.

For instance, "after breast reconstruction following a mastectomy, certain motions may be challenging or impossible to perform, so stretching and strength training need to be personalized to reflect how the body has changed," explains Kaelin.

For those who have not previously exercised or are fatigued by treatment, Kaelin prescribes a three-part program, including walking with a pedometer to count daily accumulated steps, stretching to regain shoulder range-of-motion and comfortable upright posture and light strength training to avoid muscle deterioration.

Breast cancer survivors who exercise together are often more successful in maintaining their program long term, she notes.

"The exercise objective is to improve your overall health--reducing breast cancer recurrence, maintaining a healthy weight, keeping the heart fit--so you are stronger from the day of your diagnosis forward," explains Kaelin.
