I too, had a neuroendicrine tumor in my pancreas that was removed in 2002. It spread to my liver and I had many treatments done over the past 3 years to get rid of recurring liver tumors. (embolization, RFA) I eventually got approved for a liver transplant in December and had surgery in March. I had started taking a nutritional supplement called Ambrotose (a glyconutrient)last fall. When they biopsied my liver after the transplant, they said the tumors had actually developed a hard shell around them and were dying off. That's what I was told the Ambrotose would do. I still take it. Our bodies will always have the potential to make more cancerous cells, but I believe this supplement will prevent more from growing anywhere else. You might want to check into it if you're concerned about it spreading. It is also very effective for people taking cancer drugs or chemo. It helps your body to recover more quickly.
