2 years ago I went to ER with severe stomach pains, loss of weight, very tired. I was told that night that I had pancreatic cancer and was referred to a gastro Dr. She looked at the test results from ER and said I don't have cancer. She saw some inflammation of the pancreas. No meds. I got better for a while and it started up again. It has now returned again still having weight loss. I have severe stomach pain, back pain, loss of appetite. I need to know whats going on with me. What test will show if I have pancreatic cancer?
