About the International Cardio-Oncology Society

We take cancer survival to heart.

Globally, there are nearly 50 million cancer survivors, resulting, in part, from extraordinary advancements in oncology treatments.

The International Cardio-Oncology Society is committed to raising awareness about cardiovascular disease that commonly occurs in patients undergoing treatment for cancer. The ongoing success and complexity of current life-saving therapies has led to the recognition by healthcare providers, patients, and caregivers that cardiac health is vitally important in order to obtain the best patient outcomes. We aim to enhance recognition among providers that prevention and early detection of cardiovascular disease is essential to providing optimal protection for our patients.

Cardio-Oncology promotes collaboration between oncologists, hematologists, and cardiologists to protect the cardiovascular health of all patients who are undergoing or have undergone cancer therapy.



Our Vision

Eliminate cardiovascular disease as a barrier to effective cancer therapy in all of our patients being treated or who were previously treated for cancer.

Our Mission

IC-OS exists to advance cardiovascular care of patients with cancer and survivors by promoting collaboration among researchers, educators, and clinicians around the world.

What Is Cardio-Oncology?

Cardio-Oncology is the collaboration between oncologists, hematologists, and cardiologists to effectively and proactively protect the cardiovascular health of patients with cancer.
