Can Cancer Treatment Affect Your Heart?
Cancer treatment saves lives. But many patients and their families have a very valid question: can these treatments affect the heart?
Dr. Nikhila Pachani, Consultant Interventional Cardiologist at Backbone Medicity Hospital, Rajkot, recently addressed this important topic — and the answer is worth knowing.
How Cancer Treatments Can Stress the Heart
Some chemotherapy medicines and radiation therapy, while highly effective against cancer, can put stress on the heart over time. This is not true for every treatment or every patient, but it is a real concern that doctors take seriously.
The possible heart-related effects include:
- Weakening of the heart muscle — the heart may not pump as strongly as before
- Rhythm problems — the heartbeat may become irregular
- Rise in blood pressure — which can add extra load on the heart
These effects depend on several factors — the type of cancer drug used, the dose given, and whether the patient already had any existing heart conditions before treatment began.
Not Everyone Is at the Same Risk
It is important to understand that not every cancer patient will develop heart problems. Risk varies from person to person. Some drugs carry a higher risk than others. Patients with pre-existing heart disease may need closer monitoring than those with a healthy heart.
This is why the field of Cardio-Oncology has grown so much in recent years. It focuses on protecting the heart while treating cancer — so patients do not have to choose between the two.
Why Heart Check-Ups During Cancer Care Matter
Dr. Pachani highlights that heart check-ups before, during, and after cancer treatment play a key role in early detection. If a problem is caught early, it can often be managed before it becomes serious.
Early heart monitoring helps doctors:
- Set a baseline of how the heart is working before treatment starts
- Track any changes in heart function during treatment
- Catch and address issues quickly after treatment ends
The goal is simple: protect both life and heart at the same time.
A Note for Patients and Families in Gujarat
If you or a loved one is undergoing or planning cancer treatment, do not ignore heart health. Talk to your oncologist and ask whether a cardiologist should also be part of your care team.
For personalised guidance, consider booking a consultation with a qualified cardiologist who can assess your individual risk.
