Brief Summary:
After locating the suspicious lesion/mass with standard of care mammography and/or ultrasound, a photoacoustic scan will be performed in the breast where the lesion is located. After the PA scan a biopsy will be performed, if clinically indicated (based on the mammogram and ultrasound only).
