Construction of an Ultrasound Profile and a Mammographic Profile Corresponding to the Different Molecular Subtypes of Brest Cancer. A Retrospective Study

Study Overview
=================
Brief Summary
-----------------
PROFILS is a retrospective, exploratory study on data collected in 203 breast cancer cases diagnosed during a national screening campaign from 2015 to 2018. The aim of the study is to analyse histological, clinical and radiological data collected during the screening campaign to build an ultrasound profile and a mammographic profile corresponding to brest cancers' different molecular sub-types (Luminal A, Luminal B, HER2+, Triple negative) using the BI-RADS classification. The study has the following objectives: To compare molecular profiles of breast cancers detected in a cohort of women diagnosed with tomosynthesis and ultrasound with molecular profiles of brest cancers detected in the cohort of women diagnosed with classical mammography and ultrasound To describe molecular profiles of cancers detected only with ultrasound,
