The Effects of Upper Limb Exercise Through Yoga on Limb Swelling in Chinese Breast Cancer Survivors – A Pilot Study

Abstract

Breast cancer is the most common female cancer. The aim of this study was to assess the impact of yoga on lymphedema in breast cancer survivors. Repeated measures before and after the intervention. We enrolled 15 women with breast cancer who had not previously worn elastic clothing to treat lymphedema. The program was led by a certified trainer and consisted of 60-minute sessions, three times a week for 12 weeks. The volumes of the affected and normal limbs were measured. A self-assessed edema score was also recorded. Fifteen patients completed the program, none of whom suffered from complications related to exercise. There was no significant edema after exercise. No significant differences were noted in subgroup analysis by age or the affected arm. Yoga does not induce lymphedema. Lymphedema is usually treated with uncomfortable elastic clothing, and high-resistance exercise may induce edema. Yoga may be suitable for these patients.
