This is an open, multicentric, interventional, prospective, non-randomized clinical investigation. The first aim of the study is to confirm that MammoWave reaches sensitivity\>75% and specificity\>90% in breast cancer (BC) detection on 10.000 volunteers undergoing regular screening programs.
MammoWave is a non-CE marked device that uses low-power (1mW) microwaves (1-9 GHz) instead of ionizing radiation (X-ray) for BC screening. MammoWave uses safe low-power radio frequency signals in the microwave band; it is a Class IIa medical device (non-invasive device). The previous generation of MammoWave had obtained the CE mark; in this investigation, the device contains the same hardware and will be used with the same acquisition method as the CE marked device, but additional data processing software will be used. The 10,000 volunteers undergoing conventional breast screening examination will also undergo the MammoWave exam. The MammoWave results (WSF: breast With Suspicious Finding,i.e. with suspicious lesion, or NSF: No Suspicious Finding, i.e. breast without lesion or with low suspicious lesion) will be checked against the Reference Standard, to be intended as the output of conventional breast examination path (i.e., screening mammogram, integrated with other radiological/histological output when deemed necessary by the responsible Investigator in each site). Reference Standard may be BC+ for the histology-confirmed breast cancer (BI-RADS 6); BC- otherwise (BI-RADS 1, 2, 3). (NOTE: BIRADS 4 and 5 are only image suspicion criteria: when a biopsy is performed, BIRADS are transformed in 6 (BC+) or 1,2 and 3 (BC-)) This clinical trial is performed within MammoScreen project \[1\] awarded in the context of HORIZON-MISS-2021-CANCER-02-01.

Purpose
SCREENING
Masking
NONE
Women undergoing conventional breast screening examination will be asked by the clinical staff if they are interested in taking part in the study. A short visit should be performed to check the inclusion/exclusion criteria, review demographic data, and the volunteer's medical history. After performing this visit, the volunteers will perform the MammoWave exam on both their breasts. The exam will be composed of two phases: data acquisition and data processing. During the acquisition, which should take about 8 minutes, the volunteers would be lying down in a prone position, on the bed which is part of MammoWave. When the acquisition is completed, the data will be processed through a dedicated microwave imaging algorithm. The output will be composed of microwave images, plus parameters describing the images. MammoWave output will also comprise a label obtained using an optimized classification algorithm.

MammoWave® sensitivity
MammoWave® sensitivity (percentage of 'true positive' results) while using an optimized classification algorithm. The Reference Standard is intended as the output of conventional breast examination path (i.e. screening mammogram, integrated with other radiological/histological output when deemed necessary by the responsible Investigator). Reference Standard may be: BC+ for the histology-confirmed and classified as BI-RADS 1,2 or 3.

MammoWave® specificity
MammoWave® specificity (percentage of 'true negative' results) while using an optimized algorithm.
Time frame: During the procedure
Detection rates by type of lesion
Evaluation of the detection rates (sensitivity) according to the type of radiological finding (microcalcification, mass, asymmetry or architectural distortion group), also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
Time frame: During the baseline
Recall rate
Evaluation of MammoWave recalls, also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
Time frame: During the baseline
Positive-predictive value
Evaluation of MammoWave positive predictive value (for the biopsies performed), also by breast density (according to BI-RADS ACR classification assigned by the radiologist), and comparison with the other standard screening and diagnostic modalities.
