Hi,
You may want to get a second opinion regarding your mom's pancreatic tumor. Every case is different, but when they removed my pancreatic tumor, they also removed the liver lesions that I had at that time to try and keep them from spreading. When cancer cells get into the liver, they continue to spread because the liver is always regenerating its cells. It can further spread to other organs and the lymph system. Mine were lesions, too, but there are ways to treat them.
