High-risk women’s risk perception after receiving personalized polygenic breast cancer risk information

Abstract

Evidence is accumulating of the clinical utility of single nucleotide polymorphisms to effectively stratify risk of breast cancer. Yet for this personalized polygenic information to be translated to clinical practice, consideration is needed about how this personalized risk information should be communicated and the impact on risk perception. This study examined the psychosocial implications and the impact on risk perception of communicating personalized polygenic breast cancer risk to high-risk women. High-risk women with a personal history of breast cancer and an uninformative BRCA1/2 result were genotyped in the Variants in Practice study for 22 breast cancer single nucleotide polymorphis..
