ALMOST 43,000 cancers could be prevented in the year 2025 through dietary improvements and increases in physical activity alone, according to research published in the the Medical Journal of Australia.
The authors estimated the number of cancers that could be prevented by improvements in diet and physical activity. Previous international research has estimated that 25% of cancers could be prevented through changes to diet and physical activity.
Using current trends in population growth and aging, the researchers estimated there would be about 170,000 cancer diagnoses in 2025 - a 60% increase on the 2007 annual figure.
They then applied the published estimates on the association between food, nutrition and physical activity in preventing cancer.
This reduction of 43,000 cancers would equate to savings of $674 million in 2025 alone (based on 2000-2001 treatment costs ignoring inflation), which highlighted the need for governments, doctors and researchers to act now to reduce the future burden of cancer.
