pancreatic cancer? My mom was diagnosed with pancreatic cancer about 9 months ago and underwent the Whipple surgery to remove the tumor, along with most of her pancreas. She underwent chemotherapy and radiation therapy and seemed to react well to both (several CT scans have indicated no signs of tumors elsewhere in her body). However, about 2-3 weeks ago, she began experiencing a constant pain in her abdomen, which has persisted. She's gone to a few different doctors, and they can't exactly figure out what it might be - they think maybe just a pulled muscle. However, she went to her oncologist last week and found out that her CA 19-9 level shot way up. Is there something else, besides the cancer and that could be related to her stomach pain that may be causing this?
