Research progress of cardiotoxicity caused by radiotherapy in breast cancer

Abstract

Breast cancer has surpassed lung cancer as the most common type of malignancy worldwide. Treatments for breast cancer include surgery, chemotherapy, radiotherapy, targeted therapy, endocrine therapy, immunotherapy, and hyperthermia. Radiotherapy plays an important role in breast cancer treatment. Patients with early breast cancer can have longer survival after combined treatment, but cardiotoxicity caused by radiotherapy may affect long‐term prognosis. This article reviews cardiac damage caused by radiotherapy in breast cancer.
