[|Human|] well. my sister in law went through a series of operations last December to remove cancer (not sure where).  Part of the procedure was to move part of the liver.  Prognosis was good, months of chemo and all appeared good.  Today she was told that they discovered spots on her liver and an immediate biopsy is needed.  What are they concerned with and can these spots be benign and harmless.  what is the likelihood of something more severe?   Thankss!
[|AI|]  Hi and welcome to Chat Doctor. Thanks for the query. I am afraid there is significant risk that these are something more serious such as metastases. But it must be evaluated, and only biopsy can confirm it. If these spots were not in liver during the operation then it is not likely to be simple cysts or hematomas but as I said, everything is possible in such cases. Hope I have answered your query. If you have any further questions I will be happy to help
