Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Breast cancer is the most common cancer in women. In Italy, women are invited to a population-based mammography screening programme for the first time at the age of 45 or 50 years. Results from randomised controlled trials, observational studies, and systematic reviews continuously fuel the debate on the balance on benefits (reducing breast cancer mortality) and harms (overdiagnosis, overtreatment) of mammography screening. Physicians, policy makers, as well as laypeople or patient associations agree on the need to inform women about the potential benefits and harms in order to allow an aware decision process. Decision aids are an effective way to support lay people in their decisions about health.

Decision-aid

Group Type EXPERIMENTAL

Decision-aid

Intervention Type OTHER

Web platform with a multilevel information and an aid for the decision to be taken. The content is splitted in 16-20 screens; each screen contains the answer to a common question (i.e. What is mammography screening? What are its benefits and harms? What results can be expected from the participation to mammography screening? What is breast cancer?). The information covers also controversial topics as overdiagnosis, overtreatment and the disagreement among scientists about harms and benefits' quantification.
