The purpose of this study is to validate the interest of broadband spectroscopy analysis (femto/attosecond by infrared laser) on liquid biopsies in breast cancer screening.


Each patient will have one or more liquid biopsy during the follow-up according to the cohort and have a mammogram at the same time.

Biopsies will be analysed by broadband spectroscopy in order to compare the results to mammogram result.
