Background: Breast is the commonest site of cancer in females. With new advanced and more efficient surgical and medical treatments the survival rate has improved. The adverse effects of cardiotoxic nature of adjuvant therapies results in depreciated cardio pulmonary capacity and worsening quality of life. Purpose: To determine the effects of exercise training on cardiopulmonary function and quality of life in stage II and III breast cancer survivors who had completed surgery (modified radical mastectomy-MRM), chemotherapy and are currently on radiation therapy. Methods: 30 Breast cancer patients were randomly assigned to an exercise (n=15) or control (n=15) group. The exercise group received exercise training thrice a week at initiating intensity of 13 RPE upto 15 RPE in time frame of 4 weeks. The control group did not train but was at conventional treatment as at DHRC. The primary outcomes were changes in peak oxygen consumption and overall quality of life from baseline to post intervention. Peak VO2 was assessed by submaximal exercise Half mile walk test and quality of life by using SF-36 questionnaire. Results: All 30 patients completed the trial. The baseline values for peak VO2 (p=0.656), PCS (p=0.582) and MCS (p=0.389) scores of quality of life did not differ between groups. Peak VO2 increased in exercise group and decreased in control group [mean difference of 3.509ml/kg/min; CI=95%; p<0.001]. PCS and MCS increased in exercise group and decreased in control group [mean difference of 10.86 and 14.78 respectively with CI=95% and p<0.001]. Conclusion: Exercise training had beneficial effect on cardiopulmonary function and overall quality of life in breast cancer females
