question: I am a 62yr. old female diagnosed with stage IV colon cancer in 2006. Metastases was to the liver, omentum, lining of the pelvic floor, and 3 out of 15 lymph nodes, along with the colon. I have had a colon resection and aggressive chemo then remained on maintenance chemo until 2009 when I had a recurrence in the right ovary. I had a hysterectomy and another 6month regimen of chemo. Since that time I have been on maintenance chemo. Had a surgery to remove extensive scar tissue and part of the small bowel due to freq. bowel obstructions. My only symptoms of gluten intolerance could also be due to the chemo so I m wondering if I have some intolerance. I do get some discomfort after eating, had freq. constipation until I began taking probiotics and sometimes Metamucil. I now have a ventral hernia and don t have as much constipation. Now I have lower left quadrant pain off and on. The Pet Scan showed something in the colon but the colonoscopy showed nothing. My CT Scan showed small lesions on my liver and kidney which are too small to determine what they are. I already had some cysts on my liver and kidneys but these are new. My CEA goes up and down from 3.4 to 4.3. My CEA when diagnosed with stage IV was only 7.6 so my doctor has increased my chemo and may go to other drugs but I am anxious about that because no one can determine if I have cancer or not. Do you have any thoughts about it?
