I read your post and wanted to add a thought.
My dad went into surgery (may 20th) for gall bladder removal and to remove the top 1/3 of his liver(where they found a spot). It ended up being gall bladder cancer that had spread to the liver. They removed the gall bladder and as much of the liver as they could. Gave him 3-6 months.
Today is his last (20 sessions) of daily radiation and oral chemo(Xeloda).the doctors told him that with his treatment he was now looking at 60% survival. good odds I thought. The cancer can not be cured, but kept in check. we hope now. he will have to go back (not sure) weekly or maybe monthly for a radiation round at Duke.
There is hope for gall bladder cancer. His was apparently caught very early. His radiation did not make him sick, or any any problems so far.
We are excited and blessed to see his progress.
Hope this helps other readers.
