Introduction: The primary objective of radiation therapy (RT) is to deliver lethal radiation doses to abnormal cancer cells so that healthy cells are exposed to minimal radiation. In the present study, changes in electrocardiography (ECG) and echocardiography(ECHO) following adjuvant RT were investigated in patients with left-sided breast cancer.
Materials And Methods: 30 patients with left-sided breast cancer who had previously undergone breast-conserving surgery or mastectomy underwent RT after completing chemotherapy from February 2019 to January 2020.
