Hi there.
I understand your concern.
Your present symptoms are really very non-specific to point out to something specific such as pancreatic cancer. Also, given your complex history of systemic diseases, these pains may be a complication of these (like autoimmune vasculitis or inflammation at other sites) rather than a pancreatic cancer. If ever your pancreas is ever involved, I think it will be likely due to pancreatitis rather than cancer. These symptoms may also point out to a gallbladder problem.
Nevertheless, I respect your doctor's views regarding your situation, and he has your best intentions in mind in requesting these tests. Let's just hope that all the tests will turn out fine.
Wishing you all the best. Regards and God bless.
