If participant agrees to take part in the study, a piece of the tumor that is removed during the biopsy will be collected for research purposes. The tissue will be sent to the laboratory for genetic testing.
If they have had a computed tomography scan (CT scan) or magnetic resonance imaging scan (MRI) recently, information collected from the scan will be collected. If they have not had one recently, they will have an MRI with contrast as part of this study. They will receive a separate consent form for this MRI scan.
The results of the test will be given to their doctor, but the results will not be used to decide their treatment.
After they have surgery, information will be collected from their medical records, such as their diagnosis.
Length of Study:
* Their participation on this study will be over once their surgery is completed.
* This is an investigational study.
Up to 100 participants will take part in this study. All will be enrolled at MD Anderson.
