A Clinical Investigation to Evaluate Microwave Imaging Via MammoWave® in a Population-based Screening Program for Early Breast Cancer Detection

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-))
