Abstract

BackgroundBreast cancer risk education enables women make informed decisions regarding their options for screening and risk reduction. We aimed to determine whether patient education regarding breast cancer risk using a bar graph, with or without a frequency format diagram, improved the accuracy of risk perception.

MethodsWe conducted a prospective, randomized trial among women at increased risk for breast cancer. The main outcome measurement was patients- estimation of their breast cancer risk before and after education with a bar graph BG group or bar graph plus a frequency format diagram BG+FF group, which was assessed by previsit and postvisit questionnaires.

ResultsOf 150 women in the study, 74 were assigned to the BG group and 76 to the BG+FF group. Overall, 72% of women overestimated their risk of breast cancer. The improvement in accuracy of risk perception from the previsit to the postvisit questionnaire BG group, 19% to 61%; BG+FF group, 13% to 67% was not significantly different between the 2 groups P = .10. Among women who inaccurately perceived very high risk ≥ 50% risk, inaccurate risk perception decreased significantly in the BG+FF group 22% to 3% compared with the BG group 28% to 19% P = .004.

ConclusionBreast cancer risk communication using a bar graph plus a frequency format diagram can improve the short-term accuracy of risk perception among women perceiving inaccurately high risk.
