The majority of Danish breast cancer survivors on adjuvant endocrine therapy have clinically relevant sexual dysfunction: a cross-sectional study.

Background: Impairments in sexual function are common among breast cancer survivors (BCSs), particularly in BCSs receiving adjuvant endocrine therapy (AET). Whether these impairments cause distress, thus qualifying for a more clinically relevant diagnosis of sexual dysfunction (SD), is inadequately described among BCSs and represents an important research gap. Hence, the primary aim of this study was to estimate the prevalence of clinically relevant SD, in this context: impairments with associated distress, and to identify factors associated with SD among BCSs on AET.
