Significant advances in technology have allowed radiation therapy to be administered in a way that minimizes
cardiac dose and the risk of late cardiovascular complications while providing tumor control. Various
treatment methods can be used to reduce the heart dose in the treatment of breast cancer and thoracic
tumors with radiation. Deep inspiration breath hold technique, application of radiotherapy in the prone
position, accelerated partial breast irradiation are frequently used methods in the treatment of breast cancer.
Intensity-modulated radiotherapy and proton therapy have been shown to reduce the cardiac dose in
many diseases such as breast cancer, lung cancer, esophageal cancer, mesothelioma, bilateral lung irradiation,
lymphoma, and craniospinal irradiation. The best cardioprotective technique should be used by evaluating
patient characteristics (age, comorbid diseases, and patient"s anatomy) and technical possibilities.
