Impact of awareness of cancer among acquaintances on cancer screening attendance.
Two nationwide observational surveys were carried out in France in 2005 and 2008 with the aim of assessing the impact on attitudes towards cancer screening of a positive history of cancer among a person's close circle of acquaintances (relatives, friends or colleagues). In 2005, 67% (993/1482) of people interviewed reported having someone in their close circle of acquaintances affected by cancer and in 2008, the rate was 80% (1158/1454). In 2008, having someone within a person's close circle of acquaintances affected by cancer did not increase the rate of screening for breast cancer (already high at >80%). However, it did increase the rate of screening for colorectal cancer [odds ratio (OR)=2.3; 95% confidence interval (CI)=1.6-3.3] and prostate cancer (OR=2.2; 95% CI=1.4-3.5). Knowing someone affected by cancer within the close circle of acquaintances clearly increases awareness, and thus could be an incentive for undergoing cancer screening. With regard to cancer types, such as prostate cancer, for which there is no national programme or media communication, this awareness might be the main source of information and motivation. The impact of awareness on screening behaviour seems to be greatest for the same cancer location as that in the affected acquaintance, as opposed to cancers at other sites. Increased awareness as observed in our survey, which may be attributable to less social stigma associated with a diagnosis of cancer, might increase the rate of screening attendance in the general population.
