I was diagnosed with pancreatic cancer at Kaiser in 2016.

If I were you, I would first request an appointment with your GP and ask for an explanation of the radiologist's report. If you are not satisfied, you can readily switch to another GP. You could ask for a referral to a gastroenterologist (the report you received mentions possible advice from a gastroenterologist).

I went to a Kaiser emergency room to accelerate my diagnosis. A friend also did this. It helped both of us.

I sought opinions outside Kaiser at a few points, but I had to pay for them.

Good luck.
