I'm not sure, off the top of my head, what the different treatment options are, but you can get this information from two organizations that I know of. The first is the American Cancer Society (1-800-ACS-2345 or [url="http://www.cancer.org)"]www.cancer.org)[/url] or The National Cancer Institute, which also has more information on clinical trials (1-800-4CANCER). Good luck!
