Heart-Healthy Habits Slash Early Death Risk for Cancer Survivors

Cancer survivors can lower their risk of early death by adopting heart-healthy habits. A new study in the European Heart Journal highlights how simple lifestyle changes may improve long-term survival after treatment. Researchers found that better cardiovascular health directly links to a reduced chance of mortality in this group.

The findings suggest that even small, steady improvements in diet, exercise, and stress management can make a lasting difference.

The study focused on seven key principles for heart health, known as Life’s Simple 7. These include eating well, staying active, avoiding tobacco, keeping a healthy weight, and controlling blood pressure. Survivors who followed these guidelines closely saw a 38% lower risk of death compared to those with poor heart health. Each one-point gain in their Life’s Simple 7 score also cut cancer-related mortality by 10%.

Among the most effective changes was following a Mediterranean-style diet. Rich in fruits, vegetables, whole grains, and lean proteins, this eating pattern showed an even stronger link to longer survival. Experts stress that personalised adjustments—such as tailoring meals to energy levels or symptoms—can help survivors stick to healthier routines.

Beyond diet, regular physical activity, stress reduction, and adequate sleep were also highlighted as critical. Since cancer and heart disease share risk factors like obesity and smoking, integrating heart health into cancer care could offer broader benefits. The research underscores that gradual, sustainable changes matter more than drastic overhauls.

For cancer survivors, prioritising cardiovascular health may extend life and reduce complications. The study’s results point to clear, actionable steps—from better nutrition to quitting smoking—that can be adapted over time. Healthcare providers are now encouraged to include heart health guidance as part of standard cancer follow-up care.
