Photoacoustic Imaging of the Breast in Patients With Breast Cancer and Healthy Subjects

This trial studies photoacoustic imaging of the breast in patients with breast cancer and healthy subjects. Dense breasts typically reduce the sensitivity of a mammography and also is associated with a higher risk of breast cancer. Photoacoustic tomography combines light and sound to provide more information about breast tissue.

Inclusion Criteria: * Women with clinically suspicious or confirmed breast cancer masses (that have not been surgically removed) and will/have already undergo/undergone breast magnetic resonance imaging (MRI). Exclusion Criteria: * Pregnant women (there are no known risks to these procedures, but any unforeseen risks are as yet undetermined, so pregnant women will be excluded by means of a verbal confirmation at time of screening). * Women who have had breast implants in the previous 6 months. * Women who have had lumpectomy * Adults unable to consent. * Individuals who are not yet adults (infants, children, teenagers). * Pregnant women. * Prisoners. * There is no direct benefit of the study to any subject either non-English or English speaker. To facilitate the consent process, we will exclude non-English speaking subjects.
