marty, i'm sorry to hear about
your dad.
my dad had a bleeding tumor and part of his colon removed in march of this year. unfortunately, the cancer had spread to some of his lymph nodes and his liver. he recovered really well from his surgery and has been on chemo for about 6 months now. but, he feels good most days. just more tired and some side effects. prior to finding the polyp, my dad was more tired and looked pale - turns out, he was severely anemic. he's recovered from that as well. his most recent cat scan show that the spot on his liver is shrinking. so, that was good news!! :)
of course, i'm not saying your dad is in the same situation...i just want you to take comfort in knowing that your dad (and you) are not alone. just take it day by day, and be there to support him...and he'll get through this. he may just have surgery and that's it. keep us posted... and if you have any questions about anything, don't hesitate to ask. :)
