Introduction: Cardiovascular diseases and cancer are the main causes of death in developing countries. In Brazil, until this year, 66,280 new cases of breast cancer are expected. With advances in the treatment of the disease, there has been an increase in survival. However, the treatment causes harmful effects on the clinical condition of these patients. Thus, physical exercise is pointed out as a strategy to minimize these effects. Objective: To carry out a narrative review of the scientific literature to identify the effects of physical exercise on cardiac autonomic modulation and phase angle of women with breast cancer. Materials and Methods: A search was carried out in the Lilacs and Capes Periodicals Portal; seven articles were selected for this review. Results and Discussion: Supervised and unsupervised, aerobic, strength, flexibility and balance exercise programs are effective to improve physical fitness, reducing fatigue and improving psychosocial aspects in breast cancer patients undergoing treatment. We did not find studies that addressed the effects of physical exercise on the phase angle and cardiac autonomic modulation of patients with breast cancer undergoing treatment. Conclusion: Physical exercise is shown to be an effective non-pharmacological alternative on the clinical aspects of women with breast cancer undergoing treatment. An approach to the assessment of heart rate variability and body composition, through electrical bioimpedance, seems to be substantial for the follow-up and better care of these patients. Research is needed that addresses the effects of physical exercise on the phase angle and autonomic modulation of women with breast cancer, to investigate whether exercise can minimize the deleterious effects caused by the treatment of the disease.
