Primary Objective: \- To perform a prospective study to determine if there is a different in the marker clip migration if the first post-biopsy mammogram was performed in the same projection as the core biopsy versus in the orthogonal projection.

You are scheduled to have a biopsy because a lesion was seen on your mammogram. Sometimes, the lesion is completely removed during the biopsy. Therefore, a clip is usually placed to mark the biopsy site. If some of the tissue in this area needs to be removed by a surgeon at a later date, the clip will mark the area for your surgeon to remove. All participants in this study will already be scheduled for a stereotactic biopsy with clip placement followed by a mammogram, as a part of the standard of care. You will need to sign a separate consent document for these procedures. Before you can start treatment on this study, you will have screening tests. These tests will help the doctor decide if you are eligible to take part in this study. Blood (about 1 teaspoon) will be drawn for routine tests. Women who are able to have children must have a negative blood (about 1 teaspoon) pregnancy test before they can take part in this study. If you are eligible and you choose to take part in this study, you will be randomly assigned (as in the toss of a coin) to one of two study groups. There will be an equal chance of being assigned to either group. If you are assigned to Group 1, your breast will be compressed the same way as the breast was compressed during the biopsy in the first mammogram picture. In the second picture, your breast will be compressed the opposite way (a 90-degree rotation) from the way the first picture was done. If you are assigned to Group 2, your breast will be compressed in a 90-degree rotation from the way the breast was compressed during your biopsy in the first mammogram picture. In the second picture, your breast will be compressed the same way as during the biopsy. A researcher will review the mammogram to measure and record the distance of the biopsy clip from the biopsied lesion. If your biopsy is benign (non-cancerous), you will return to the clinic for a mammogram once a year, as is standard of care. Researchers would like to review the mammogram that is taken 1 year after the biopsy in order to check to see if the clip has moved or stayed in the same place. This is an investigational study. The clip used in this study is FDA approved. Up to 60 patients will take part in the study. All will be enrolled at M.D. Anderson Cancer Center.
