Cookiegnias, I had this upper right quadrant belly pain and it was worse when lying down, and unrelated to eating. I also had changes in digestion. I had abdominal ultrasound, colonoscopy and stomach scope but all were normal. Physician was ready to stop testing (I believe stomach pain and digestive issues are easy to dismiss) but I insisted something was not right and we finally did CT scan which detected the tumor. Time of onset of symptoms to identification of the cancer was 5 months. We need to be our own advocates in the health care world.
