 Subjects will have to go to nearby hospital within 1 week of completing Visit 5 to have this outpatient procedure done. Subjects will be asked to lie on their stomach face down with a pillow under their rib cage for at least 20 to 30 minutes. Ultrasound may be used to find the proper biopsy site. A local numbing medicine anesthetic will be injected under their skin near the biopsy area.
