Chemotherapy is one of the most common forms of cancer treatments, but it's not without side effects. Although chemotherapy side effects differ depending on the type of cancer a patient is fighting, their general health, and chemo type and dosage, many people are vulnerable to heart damage. In fact, certain types of chemotherapy drugs actually increase the likelihood of heart damage. 

When a heart becomes damaged by chemotherapy drugs, the organ struggles to pump blood throughout the rest of the body. This can result in a buildup of fluid and other issues that contribute to congestive heart failure. It's important to note that not every chemotherapy drug results in heart problems.
