Cancer and cardiovascular diseases share a complex relationship, as cancer treatments can have profound effects on heart health. Certain chemotherapy drugs and radiation therapies are known to increase the risk of cardiovascular complications, including heart failure and coronary artery disease. Research is focused on understanding how cancer therapies affect the cardiovascular system, particularly the long-term risks faced by cancer survivors. Cardiovascular monitoring during cancer treatment is essential to detect early signs of heart issues. Additionally, studies are exploring strategies to reduce cardiovascular risks, such as the use of cardioprotective drugs and lifestyle interventions. This interdisciplinary approach aims to improve the overall health of cancer patients and survivors, ensuring that their heart health is closely managed alongside cancer treatment.
