my dad is getting whipple surgery? please answer?

hes 50 and hes a alcholic (sp?)
hes been drinking for like 30 years now
and he might have cancer in the pancreas
well thats what my mom says anyway
but im pretty sure he does, why else would he be having this surgey?
my mom wont tell me anything about it, other than its gonna be a long and painful surgey and hes gonna stay in the hospital for over a month
so tell me what are they gonna do, and is he going to be okay in the end? what are the chances? im fifteen years old
