My dad has had 3 CT scans (abdominal pain); 2005, 2008, May 2009. His last colonoscopy
(all negative findings) was also in 2005. Over the past three months, he has had increasingly worse abdominal pain, mostly left lower quadrant with radiation to his rectum. No jaundice, no weight loss, no back pain, no change in stools. His physician at that time ordered the latest CT scan.
