I need some advice. This is my third go round with thy ca. first in 77, then in 95 with mets to nodes. Now I have rising tg and neg scan. I was told that I don't take up iodine. My Tg is now at 32.5. I was told to seek out other opinions at Mayo and MD Anderson. I live in Calif. How can I be treated if the dr cannot find the mets. Any advice would be great.
