My dad was diagnosed with colon cancer last monday, he went for the procedure to have a camera imserted but they couldnt het the camera through as the tumour was too big, his colon is has been reduced in size massively. The doctor took 10 biopsys but told my dad he didnt really need them and has seen enough cancer to know. 
he has now had a CT scan where they also used some dye i believe this is too see if the cancer has spread to any organs, the results ho infront of the MDT for discussion today. 
im concerened that if its that big does this suggest his in a later stage? I cant talk to him because he just wants to carry in as normal but seeing him no longer eating properly or up in the night in agony and knowing his colon is near enough closed is playing in my mind so much. 
has anyone been through this?
