Girlfriend getting very strong pain in abdomen, her sister died of pancreatic cancer a few years ago. she is 21 and vegan if this makes a difference?

Question? : What exactly is the question ? There are multiple multiple things that could be causing abdominal pain in a female. I can understand her concern due to her family history but you and her need to understand that out bodies are complex and there are many other things that could be causing her pain. I advise you to have her go to see a doctor for a physical exam and proper diagnostic studies.
