Who we are What we doFund research on the relationship of nutrition,
physical activity and body weight to cancer risk
Interpret the accumulated scientific literature to derive Recommendations for Cancer Prevention
Educate people through our national Health Information programmes
Advocate effective policies to help people and populations to reduce their chances of developing cancer

The Continuous Update Project. Aims
Ensure everyone has accessBased on the most up to date scientific evidence

• Keep evidence, conclusions and recommendations updated into the future• Working with team at ICL• Same principles: - Systematically review evidence- Meta analysis - Panel of experts
- draw conclusions - make recommendations

CUP Search Literature Review PROTOCOL(SLR- Imperial College London)
Research topic :The associations between food, nutrition and physical activity and Cancer risk Mortality and second cancers in breast cancer survivors.
Main objective :Summarize the evidence from prospective studies and randomised controlled trials (case-control studies if requested by the Panel).
Search strategy:Medline, Central, ClinialTrials.govHand search of references (reviews, meta-analysis, recent relevant papers)
