Study Links Unhealthy Lifestyle to 51% of Diabetes Cases in 18,664 Childhood Cancer Survivors

An analysis of 18,664 childhood cancer survivors found unhealthy lifestyle habits were tied to higher risks of hypertension, diabetes, heart attack, heart failure, valve disease, joint replacement, anxiety, depression, and poorer physical and mental quality of life.
The strongest relative increases included diabetes at 2.8 times the risk, impaired physical quality of life at 2.1 times, and anxiety and valve disease at 1.8 times versus survivors with healthy lifestyles.
Lifestyle accounted for a larger share of disease than chemotherapy and radiotherapy for several outcomes, including 51% of diabetes, 22% of hypertension, 28% of joint replacements, and 26% of anxiety cases.
Overweight or obesity and low physical activity drove most of the excess risk, outweighing smoking and risky drinking across many conditions.
The study says lifestyle is a modifiable factor unlike past cancer treatment, suggesting survivor care should add targeted weight and exercise interventions alongside treatment-based risk screening.

Over 50% of Diabetes in Childhood Cancer Survivors Attributable to Lifestyle: New Evidence Calls for Urgent Intervention
Overview
A major international study published in May 2026 revealed that while life-saving treatments are essential for childhood cancer patients, they often leave survivors at higher risk for chronic health problems like cardiovascular disease. The research followed over 18,000 survivors and found that lifestyle factors play a critical role in long-term health, with 51% of diabetes cases among survivors directly linked to unhealthy habits such as obesity and low physical activity. This highlights the urgent need for proactive lifestyle management, as healthy choices can significantly reduce preventable risks and improve the quality of life for childhood cancer survivors.
