The Effect on Clip Markers Migration After Vacuum-Assisted Biopsy by Postprocedure Mammogram

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.
