Study Findings

A groundbreaking study has unveiled that adopting a healthy lifestyle can significantly lower cancer mortality risk among survivors, particularly for those diagnosed with obesity-related cancers. The American Cancer Society (ACS) revised its nutrition and activity guidelines in 2022, urging cancer survivors to maintain a healthy weight, engage in regular physical activity, consume a nutritious diet, and limit alcohol consumption.

In this illuminating research published in the Journal of the National Cancer Institute, ACS scientists found that non-smoking cancer survivors who adhered to these lifestyle guidelines exhibited a marked reduction in mortality rates. The data suggests that survivors who not only followed a healthy lifestyle prior to their diagnosis but also made improvements post-diagnosis were at an even lower risk of mortality.

Expert Insights

Dr. Ying Wang, a senior principal scientist in epidemiology research at the ACS and the study’s lead author, emphasized the transformative power of lifestyle changes: 'A cancer diagnosis often motivates people to think about how they can live healthier lives. Many survivors want to know what lifestyle changes they can make to improve their chances of living longer. These findings underscore how making the right lifestyle choices truly affects cancer survival.'

Study Methodology

The research analyzed lifestyle habits of non-smoking participants from the Cancer Prevention Study-II Nutrition Cohort, focusing on those diagnosed with obesity-related cancers between 1992 to 2002 and followed through to 2020. The study looked at a comprehensive range of factors—including body mass index (BMI), physical activity levels, dietary choices, and alcohol consumption—rating participants on a scale from 0 to 8 based on their adherence to the ACS guidelines.

Key Results

Results from the analysis of 3,742 cancer survivors, with an average age of 67.6 years and a median follow-up of 15.6 years, revealed that 2,430 participants had died during the study period. Notably, survivors who achieved a score of 6-8 experienced a staggering 24% reduction in all-cause mortality risk (HR = 0.76; 95% CI = 0.68 to 0.85). Furthermore, they had a 33% lower risk of death from cardiovascular diseases (HR = 0.67; 95% CI = 0.54 to 0.83), and a 21% reduction in risk of cancer-specific mortality (HR = 0.79; 95% CI = 0.64 to 0.97) compared to those scoring 0-3.

Conclusion

This compelling evidence highlights the importance of lifestyle modifications for cancer survivors. Experts urge patients to take proactive steps toward healthier living, not just in the wake of a diagnosis, but throughout their lives to significantly enhance survival outcomes. Engaging in even small, incremental lifestyle changes can lead to profound health benefits and potentially greater longevity, making it a crucial conversation among healthcare providers and patients alike.
