Assessing the Effect of an Aerobic Exercise Program on Vascular Function in Women With Non-Metastatic Breast Cancer

The goal of this clinical trial is to assess the feasibility of an 8-week aerobic exercise program and its effect on arterial function in breast cancer survivors. The main questions it aims to answer are: * Is an 8-week aerobic exercise program feasible in breast cancer survivors after the completion of chemotherapy? * Is this 8-week aerobic exercise program beneficial for vascular function in breast cancer survivors? Participants will: * Begin an 8-week aerobic exercise program, three days per week, after the completion of chemotherapy. * Visit our facility three times before the exercise program, 1 month after, and after the completion of the program. * Complete questionnaires, physical functional tests, and body composition and vascular measurements at every visit.
