As our friends at World Cancer Research Fund UK mark the charity’s 25th anniversary, founder and President Marilyn Gentry gives us her thoughts on its work as a trailblazer in the field of cancer prevention, and its future in terms of both research and health policy.
Much has been made of the fact that World Cancer Research Fund UK is now 25 years old. However, World Cancer Research Fund itself actually began its mission in 1982 in order to raise awareness of how cancer was linked to diet and nutrition.
Early observation of this link came to light as people moved from one country to another. Their cancer risks mirrored their environment and changed with new environments, thus suggesting that lifestyle might play a role in lowering or increasing cancer risk.
This observation led to the foundation of the UK-based charity in 1990, and we quickly established ourselves as the only UK cancer charity highlighting the links between cancer and diet, weight and physical activity.
We soon started speaking to scientists and health professionals about developing the research in this area, and in 1992 we funded groundbreaking studies on diet and cancer at the Universities of Birmingham, London and Belfast (all UK).
Five years later in 1997, we became the first organisation to identify the link between diet and cancer, now a widely accepted fact. All our evidence was brought together in our first major report on the subject – we called it the Expert Report.
Subsequent important research findings
Over the next 10 years, we published more important research findings, including the results of a study we funded by Professor David Gunnell at the University of Bristol (UK).
He looked at associations between adult cancer risk and childhood height, along with leg, foot and trunk length, and found that cancer risk is increased in larger children.
Although Gunnell did not recommend intervention to reduce childhood growth, he did conclude that the measurements in his research were useful tools in identifying important periods of growth in terms of later disease risk.
Collating the latest global evidence
In 2007, our evidence was updated in a new report. To develop this Second Expert Report, scientists looked at 500,000 studies related to cancer prevention, of which they concluded that 7000 met the standards for inclusion.
From an analysis of these 7000 studies, an international panel of eminent scientists was able to draw conclusions about the effect of diet and physical activity on cancer risk – conclusions that inform the recommendations that remain the basis of our message today.
Establishing scientific fact
Thanks to your support and our work, cancer prevention through lifestyle is now accepted worldwide as scientific fact and is widely discussed by cancer charities.
The World Cancer Research Fund network has invested an incredible £100 million in cancer prevention research around the world, and we continue to fund groundbreaking studies.
Only last year, our review of global evidence revealed, for the first time, the link between obesity and liver cancer. A meta-analysis of 12 studies demonstrated a statistically significant 30% increased risk of liver cancer per 5 BMI units, and the story made headlines around the world.
