Resum: Background: The decision to participate or not in breast cancer screening is complex due to the trade-off between
the expected benefit of breast cancer mortality reduction and the major harm of overdiagnosis. It seems ethically
necessary to inform women so that they can actively participate in decision-making and make an informed choice
based on their values and preferences.
The objective of this study is to assess the effects of receiving information about the benefits and harms of
screening on decision-making, in women approaching the age of invitation to mammography screening.
Methods: A two-stage, randomized controlled trial (RCT). In the first stage, 40 Basic Health Areas (BHAs) will be selected and
randomized to intervention or control. In the second stage, women within each BHA will be randomly selected (n = 400).
Four breast cancer screening programs (BCSPs) of the Spanish public health system, three in Catalonia and one in the
Canary Islands will participate in the study. Women in the intervention arm will receive a leaflet with detailed information on
the benefits and harms of screening using mammography. Women in the control arm will receive a standard leaflet that
does not mention harms and recommends accepting the invitation to participate in the biennial examinations of the BCSP.
The primary outcome is informed choice, a dichotomous variable that combines knowledge, attitudes, and intentions.
Secondary outcomes include decisional conflict; confidence in the decision made; anxiety about screening participation;
worry about breast cancer; anticipated regret; time perspective; perceived importance of benefits/harms of screening;
perceived risk of breast cancer; and leaflet acceptability. Primary and secondary outcomes are assessed 2–3 weeks after
the intervention.
Discussion: This is the first RCT that assesses the effect of informing about the benefits and harms of breast cancer
screening in Spain in women facing the decision to be screened using mammography. It aims to assess the impact of
information on several decisional outcomes and to contribute to paving the road towards shared decision-making in
breast cancer screening in our country.
