 Participating in this study will take approximately 30 minutes in addition to the time a participant would normally spend in the office. This time will be spent learning about the study, providing informed consent and receiving ABUS. In order for the study doctors to gather data on the accuracy of mammography and ABUS, they will need to collect the mammography and ABUS results, as well as results from any other breast evaluations, procedures or testing performed for the next year, until the completion of an annual routine mammogram, the results of which will also be recorded.
