Yoga Study in Breast Cancer Patients
Yoga Study in Breast Cancer Patients
This purpose of this study is to test whether a 6-month yoga program improves quality of life
 and reduces fatigue and weight gain in breast cancer survivors.
Women who are overweight or obese have a higher risk of breast cancer than normal weight
 women. Furthermore, women who are overweight or obese or gain weight after diagnosis have an
 increased risk of recurrence or dying from breast cancer compared with normal weight women.
 Yoga has been associated with reduced weight gain and weight loss in persons without cancer.
 However, no studies have tested whether yoga leads to less weight gain or weight loss in
 breast cancer patients. Both obesity and the sequelae of breast cancer therapy can result in
 reduced health-related quality of life and severe fatigue, which may also be favorably
 affected by yoga practice. The specific aims of the proposed trial are to examine, in women
 with Stage 0-IIIa breast cancer who are at least 3 months post primary treatment for their
 disease (other than tamoxifen or aromatase inhibitors), the effects of a 6-month yoga
 intervention on health-related quality of life, fatigue, and body weight.
