Protecting your heart health during breast cancer treatment

Breast cancer patients often overlook their cardiovascular health during treatment, but it's crucial to address. Dr. Rowina Lynne Murray, a cardiologist at the Malaysian Institute of Cardiovascular Health, explains that breast cancer and heart disease share risk factors, such as obesity, smoking, and an unhealthy diet. Certain hormone treatments and chemotherapy drugs can raise blood pressure and cholesterol levels, while radiotherapy to the chest may damage the heart.

Cardiotoxicity affects 5-15% of women treated for breast cancer, making early detection vital. Older women and those with high blood pressure or diabetes are at higher risk. Before starting treatment, patients should discuss their cardiovascular risk with their doctor, who may recommend blood tests, ECGs, and echocardiograms to monitor heart function.

Symptoms of weakened heart health include breathlessness, swollen legs, chest pain, and palpitations. Regular echocardiograms may be required. If heart issues arise, doctors will evaluate treatment options and risks. Early detection allows for less aggressive treatment, reducing cardiotoxicity risk. Simple lifestyle changes, such as quitting smoking, limiting alcohol, eating a balanced diet, and regular exercise, can also support heart health during breast cancer treatment.
