Could this be pancreatic cancer?
I am terrified that I have pancreatiac cancer. I'm 62 y/o female, otherwise healthy except for low thyroid function. About a year ago I started feeling a dull pain in my upper left abdomen, just under my ribs. It was very mild and I felt it mostly when I was reclining in bed on my back. If I turned onto my left side, the pain would go away. I mentioned to my GP and he said it sounded like gas. Since I did pass a lot of gas, I figured he was right. During this time I also would have occasional bouts of diarrhea that would last a few days and then back to normal. Thought maybe a food intolerance or from my thyroid.
Fast forward to the beginning of this year, just after the holidays I had an episode of shapr mid-abdominal pain and again some diarrhea. Chalked it up eating too much. Then I was fine in Feb, but in early March I had an attack of abdominal pain in the upper mid abdomen again and from that day on I've had nausea and discomfort every day. Now my stomach feels either sore, burning, hard (like I swallowed a brick) or just feels weird. I have diarrhea 2-3 days and then normal stool 3-4 days and back to diarrhea.
I finally felt bad enough to see a GI doc and had the following tests: blood work, x-rays, endoscopy, colonoscopy, spiral CT scan with contrast. The results: elevated liver enzymes, small colon polyp, gastritis. Diagnosis: Gastritis and IBS. Doc gave me Protonix.
Now, 2 weeks later I still feel lousy - worse really. My abdominal pain seems to be getting worse, I have no appetite and I can't bend over without my stomach hurting. Diarrhea still comes and goes every few days. Somehow my stomach pain just doesn't feel like it's from acid. I've had GERD in the past and this feels totally different.
I know I should not look up symptoms on the internet, but every time I do it points to pancreatic cancer. I guess my question is, can an abdominal CT scan miss pancreatic cancer that is causing symptoms? Also, what other tests should I ask for?
