In the latest episode of Paul Talks Science, Dr. Helen Croker, Assistant Director of Research and Policy at the World Cancer Research Fund International, delves into the critical topic of lifestyle factors and their impact on cancer survival.
Dr. Croker explains how the World Cancer Research Fund International champions global research into the roles diet, nutrition, physical activity, and body weight play, not just in cancer prevention, but significantly, in cancer survival after diagnosis. Launching their latest reports at the World Cancer Congress, the fund specifically targeted breast and colorectal cancers due to their prevalence and the substantial role lifestyle factors appear to play.
One of the standout findings, according to Dr. Croker, is the strong evidence supporting increased physical activity for improving quality of life after breast cancer diagnosis. However, dietary evidence is still emerging, with limited but promising indications that increased dietary fiber intake may positively impact health outcomes. Dr. Croker highlighted the reassuring message on soy foods, noting no evidence suggesting harmful effects for breast cancer survivors already consuming them.
The conversation also tackled the critical issue of research integrity and the reliability of systematic reviews. Dr. Croker emphasized the rigorous processes their team employs, including transparent assessment of research funding sources and robust partnerships with leading research institutions like Imperial College London.
However, Dr. Croker acknowledged that much of the current research data is skewed towards high-income regions, underscoring the urgent need to support cancer research in lower-income countries to achieve a truly global perspective.
Ultimately, Dr. Croker sees these latest reports as vital springboards, laying the groundwork for future research and better-informed health professionals and policymakers, ultimately aiming to empower cancer survivors worldwide with practical, evidence-based lifestyle advice.
