Abstract
COVID-19 pandemic has resulted in considerable overloading of health care systems in almost all regions of the world. Among different malignancies, breast cancer can be considered as a typical example of how the decision-making process for radiation treatment can be adapted to unusual situations. There exist several international guidelines in order to modify radiotherapy treatments during the COVID-19 pandemic, however, some of their recommendations are not applicable in regions with limited resources. In this manuscript, we provided guidance to deliver radiotherapy to patients with breast cancer during the COVID-19 pandemic based on our available nationwide resources.
