Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
It involves women aged 45-46 that will be divided, by drawing lots, into two groups: one group will do the 2D digital mammography (control group), while the other group (intervention group) will do tomosynthesis. In the intervention group the 2D two-dimensional mammography will be reconstructed starting from tomosynthesis without exposing women to other radiation.

Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
45-46 year-old women resident in the screening centre catchment area of Florence and South-Est Local Health Unit are invited to attend for mammography screening and asked for informed consent to be included in the study. Women are then randomly allocated either to an usual care group (2D mammography) or to the intervention group. In the intervention group, DBT combined with sDM is proposed in order to reduce radiation exposure. The next year women of both groups will be invited to attend the usual screening examination (2D mammography). The enrolment will last 12-18 months; the whole study 36 months. The estimated sample size is 6000 women, 3000 per arm. Data will be pooled with the trial "Screening for Breast Cancer With Digital Breast Tomosynthesis", ClinicalTrials.gov Identifier: NCT02698202.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
2D mammography
45-46 years old women are invited to attend the usual screening examination (2D mammography). The next year they will be invited to make a 2D mammography, according to screening protocol.
2D mammography
2D mammography is a X-ray examinations used to detect breast cancer in the screening programme.
Tomosynthesis
45-46 years old women are invited to attend the Digital Breast Tomosynthesis (DBT) in adjunct to synthetic mammograms (sDM). The next year they will be invited to make a 2D mammography, according to screening protocol.
Tomosynthesis
DBT is a x-ray examination that allows to visualize the breast on 3 planes (3D) and therefore to help to see lesions hardly visible to mammography due to the overlap of glandular tissue.
