Hi,
Your sister has been having abdominal pain for almost 4 years now (since 2004), with normal blood results (except low vitamin B12), weight loss, headache, and no jaundice.
This makes the possibility of pancretic cancer unlikely.
It is more likely that she has some chronic gastro-intestinal condition like peptic ulcer disease.
Do you have any idea about the reason why your doctor suspected pancreatic cancer? Were any imaging studies like ultrasound or CT scan done on your sister. If so, what were the results?
The endoscopy results should shed light on the underlying diagnosis.
She should have regular small non-spicy healthy meals, take vitamin supplements, have regular exercise and sleep, and antacids if needed.
She should not stress or worry much.
And the most important thing is to ensure that she is completely investigated, diagnosed, and treated.
Pl do not hesitate to aks any other specific questions that you may have.
