Effect of interventions incorporating personalised cancer risk information on intentions and behaviour

This systematic review aimed to provide a comprehensive analysis of the impact of interventions incorporating information about cancer risk targeted at the general adult population. Randomised controlled trials that included a personal estimate of future cancer risk based on two or more non-genetic variables and one behavioural outcome were included. Of the 19 included studies, 8 investigated screening uptake. The results indicate that interventions incorporating personalised cancer risk information do no affect intention to attend or attendance at screening. Based on the smaller number of interventions that looked out these outcomes, there is limited evidence that interventions increase smoking abstinence, sun protection, and breast and skin self-examination. Further research is needed before cancer risk information is included in routine practice. Read the full article
