Being told you have cancer is a life-changing experience for most patients and leads to many new concerns such as:
Typically, concerns about the potential impact of cancer treatment on the heart are not among the first that come to mind. However, some patients with cancer may receive radiation therapy to the chest area, and these patients should be aware of the side
effects that radiation therapy may cause to the heart. These potential adverse effects are known as radiation cardiotoxicity.
Radiation cardiotoxicity may affect the heart in various ways and at any time. Some conditions develop during or soon after treatment. Others become apparent years, or even decades, after treatment. The specific adverse effects depend on which area of the heart is affected, such as injury to the heart muscle, the heart lining, or blood vessels. Examples of the conditions that may develop include cardiomyopathy, coronary artery disease, and heart rhythm problems.
Radiation treatment can be delivered using several methods. The specifics of your treatment will influence your risk of developing radiation cardiotoxicity. In addition, many other factors may increase or decrease your risk, including age, additional cancer treatments, and other heart risk factors. Your oncologist (cancer doctor), radiation oncologist (radiation doctor), or cardiologist (heart doctor) will help you understand your unique risk from radiation.
