<qa>  What is the name of the tumor that you will receive during the biopsy?Before beginning treatment on this study, you will have a biopsy of your tumor. The tissue taken during this biopsy will be compared with the tissue taken after you receive ZD6474. The tumor samples will be compared to see what effect ZD6474 has had on tumor cell death. During the biopsy procedure, you will receive either a local or general anesthetic depending on the location of your tumor and a small piece of tumor will be removed with a large needle.
