In this article I report on research investigating factors associated with participation in mammography screening in Sweden. I conducted semistructured interviews with 32 women aged 40-49 years who attended mammography screening in rural Sweden. Study participants undertook screening in the context of a health system in which women aged 40 years and above are contacted by mail with an appointment time to attend for screening. Study participants placed great value on this system, and trust was expressed in health authorities. Availability of local screening facilities was also highly valued by study participants.
