Aging of the population further adds to the number of patients being treated for cancer, especially those with comorbidities. Such pre-existing and developing cardiovascular diseases pose some of the greatest risks of morbidity and mortality in patients with cancer. Addressing the complex cardiovascular needs of these patients has become increasingly important, resulting in an imperative for an intersecting discipline: cardio-oncology. Over the past decade, there has been a remarkable rise of cardio-oncology clinics and service lines. This development, however, has occurred in a vacuum of standard practice and training guidelines, although these are being actively pursued. In this council perspective document, the authors delineate the scope of practice in cardio-oncology and the proposed training requirements, as well as the necessary core competencies. This document also serves as a roadmap toward confirming cardio-oncology as a subspecialty in medicine. Copyright (c) 2020. Published by Elsevier Inc.
