RecruitingBreast Mapping and Detection of Suspicious Breast Lesions Using FeminaiProspective observational study evaluating the safety and accuracy of Feminai 1.0, an at-home adhesive patch that measures skin temperature and electrical impedance to map each breast. Up to 300 women (ages 25-75) undergoing screening will have one study visit; Feminai results will be compared with mammography and, when available, biopsy to assess sensitivity and negative predictive value. Feminai is investigational, intended to support clinical decision-making, and does not replace standard diagnostic tests.
