[What should a cardiologist know about the follow-up and management of a woman with breast cancer ?].

Over the last decade, cancer mortality has decreased considerably, particularly in breast cancer thanks to better screening techniques and better therapeutic management. The significant increase in patient survival has led to the appearance of a certain number of events due to the side effects of the therapies used. Cardiovascular disease is the most frequently observed side effect in breast cancer, due to the direct toxicity of anti-cancer therapies but also due to traditional cardiovascular risk factors common to both of diseases. Anthracyclines, anti-HER2 therapies, chest radiotherapy and hormone therapy are the main causes of cardiotoxicity in breast cancer. It is important to know the rate of follow-up for cardiotoxicity screening and management.
