Abstract
Breast cancer is the most common cancer among women worldwide, and its incidence is linearly associated with age. The development of cancer treatments has changed the prognosis of this disease. Despite effective treatments, cardiovascular complications in middle-aged and older women have become challenging. Physical exercise is a powerful tool to prevent senescence symptoms and diseases, besides being an essential component for cardiovascular diseases and cancer prevention and treatment. The present narrative review considers the vascular dysfunction associated with breast cancer treatment, specifically chemotherapy and radiotherapy, and the effects of exercise on vascular toxicity. We also explored the mechanisms involved in these responses. The search strategy involved three databases (Pubmed, Scielo, and Web of Science) with the following descriptors: breast cancer, vascular toxicity, physical exercise, chemotherapy, and radiotherapy. The evidence showed that breast cancer patients, especially those under chemotherapy and over 50 years old, have a potential risk of developing vascular dysfunction, which may persist in the long term. Decreases in nitric oxide bioavailability and increases in oxidative stress and pro-inflammatory cytokines might mediate the chemotherapy and radiotherapy-induced vascular dysfunction. Exercise seems to be a promising strategy for managing this risk. However, there is a need for well-constructed studies evaluating vascular toxicity in breast cancer, especially in middle-aged and elderly patients, to establish whether exercise is beneficial.
