I have been diagnosed w/IBS, had colonectomy, am diabetic, high bp., now fibromyalgia, been good GI wise for over 12 yrs. Now symptoms of constipation w/diarrhea and left side pain have come back. My mother died with colon cancer that grew into the ureter and into blood vessels. Evidently, hereditary, both her brothers had colon cancer. However, she also had myelodysplastis. Should I ask Dr. To test me for it and will treatment help the colon issues?
