People are unaware of the fact that improving their diet and taking more exercise can have a beneficial effect on their risk of developing the most common cancers.
This is according to Teresa Nightingale, general manager of the World Cancer Research Fund (WCRF).
Speaking ahead of World Cancer Day (February 4th), Ms Nightingale said: "Research has shown that not enough people are aware that what they eat and how active they are affect their cancer risk."
She added that the campaigns to take place in a couple of days time will hopefully help to address this matter.
The comments follow research that revealed that while people are largely aware of the fact that smoking and sunburn were risks in developing cancer, they were mostly unaware that healthy eating, physical activity and a healthy weight can help to prevent around a third of the most common cancers.
The latest figures from Cancer Research show that in 2007 there were around 297,990 new cases of cancer diagnosed in the UK.
