Not only has it modified our current approach to life, but also it has obliged us to redefine the way by which patients with cancer are treated. Nowadays the most common worldwide cancer is breast cancer in women. Almost two million newly diagnosed female breast cancer cases were reported in 2018, accounting for almost one in four cancer cases among women(1). Currently, worldwide breast cancer centers are facing this dramatic pandemic and there is a need to re-think the approach to patients suffering from breast cancer. A large number of patients with COVID-19 required to be hospitalized and a consistent percentage of this group needed mechanical ventilation, resulting in a rapid decrease in the number of available intensive care units (ICU) and an overloading of hospital wards (2) . Therefore, it is highly required to produce appropriate protocols and guidelines to prevent the spread of the COVID-19 infection and guarantee the best healthcare system for all patients with breast cancer. Some experts have already designed general guidelines to define the best approach for breast cancer patients in this period. It has been introduced a mandatory use of personal protective equipment for medical and surgical procedures. Furthermore, the application of smart working has been implemented and only one visitor per patient has been allowed to access the hospital ward. Thus, the risk/benefit ratio should be considered according to each breast cancer patient and every step in the diagnosis, treatment and follow-up of these patients should be properly calibrated. Surely, some urgent changes in the management of patients suffering from breast cancer should be considered. First, all diagnostic procedures should be divided into urgent and not-urgent. In addition, a defined diagnostic plan should be properly established. Second, all surgical procedures and chemotherapy regimens should be reasonably programmed without compromising outcomes according to the global patient treatment process. A well-constructed therapeutic path should be taken into account, categorizing the breast cancer patients into four categories: urgent priority, surgery within two weeks, high priority, surgery within four weeks, medium priority, surgery within eight weeks, low priority, surgery after eight weeks allowed(4). Another priority for inpatient breast unit patients has been the growing shortages of medical resources and beds due to the dramatic increase in the COVID-19 patients requiring ICU beds. Some hospitals with breast care centers have had the possibility to add beds and facilities to cancer care, but other hospitals have required the reallocation of units and systems to care for patients during this health emergency. Therefore, well-designed worldwide guidelines in the diagnosis, therapy, follow-up of breast cancer patients during this pandemic period are needed to be uniformly carried out in order to provide the best care for these patients.
