Cardiotoxicity is when heart damage is caused by chemicals or medicines, like chemotherapy. When you receive chemotherapy, you are given medicines to kill cancer cells in your body. Sometimes these drugs also hurt the normal cells in and around your heart.
Cancer treatments can be hard on the body and may sometimes affect the heart. Your care team will watch your health closely during and after treatment to help keep your heart as healthy as possible. See this Cardiotoxicity & Cancer handout for more information.
