Robin,
The ER doctor can't make a statement like that. I had a liver metastases removed 5 weeks ago, but it was a single spot. What is multiple? The liver can regenerate and can be treated. I had Radio Frequency Ablation (RFA). Look it up on Google and be prepared to ask about it. Calm down and don't run from this site. I have had cancer everywhere and it has ALL been metastatic from the head and neck. I would see if you could get a PET/CT scan to rule out other areas of concern. Just so you know, my liver tumor, 3CM, appeared in a few months and did not predate the head and neck cancer.
