Brief Summary
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.

Outcome Measures
Primary Outcomes (1)
Irrational preference
Willingness to participate in mammography screening with no benefits on morbidity or mortality, only harms. Investigated by sending out questionnaire once to all women.
The outcome is assessed when women answer the questionnaire which is sent out at the same time to all women. The invited women will have 2 months to answer the questionnaire (it should only take around 15 minutes to answer). Planned from November 2020.
Study Arms (2)
Detailed information about screening harms
OTHERNon-detailed information about screening harms
OTHERInterventions
We will present an online questionnaire with two types of information on the harms of screening. Then we will compare the prevalence of irrational decisions in the two arms.
