Abstract
All fields of medicine have had to change and adapt in response to the COVID-19 pandemic. In this respect, frail and immunocompromised patients have been particularly affected. Such patients are commonly treated in oncology, a field that has witnessed a revolution in its protocols, as physicians and institutions address this new situation. This paper details the aspects of oncology that have been affected by the pandemic, in areas such as chemotherapy, surgery and radiotherapy, together with the sharp rise in the use of telemedicine. Some of these changes will probably be permanent and may even come to be seen as a positive outcome of the pandemic.
