Thanks so much for replying. Colleen saw your reply before I got here, but my questions are much like hers for now so I won't repeat them as you probably see here questions above (or below?) Any info you can tell us will be helpful. I can't remember at the moment why my Interventional Radiologist told me to try Sir-Spheres first, and if that doesn't work, we'll do TACE later. Is yours a liver tumor or elsewhere? Thanks again.
