Summary
Brief summary (as posted)
Based on an American study by Scherer et al., it is hypothesized that some women will make irrational choices regarding their participation in mammography screening. Therefore, the aim is to estimate the prevalence of Danish women having an irrational preference for mammography screening even when it confers no benefits, but only harms.
