i have not been active on this board for a very long time.... was having a 'quick look' before trying to get some sleep and saw your message. back in 2010 i had several lung lesions and had a VATS procedure to remove a section of my left lung that was then biopsied. turns out that lesion was due to a fungus infection called a MAI infection not a metastasis. i don't want to give you false hope but until one of those lung spots can be biopsied i don't think that it's 100% certain that it's a cholangio met.
i found my own tumor in dec of 2002 and have had 7 surgeries on my liver. i have now reached the point where i am no longer considered operable and am waiting to learn where i go from here. however, i've made it this long by questioning and researching, having excellent docs, and in the past learned a lot from this board.
wishing you the best
