[|Human|] In September 2014 I had a colonoscopy with pre-cancerous polyps removed. Was instructed to return in 10 years to repeat. History of colon-rectal cancer on paternal side of family. For 2 weeks now, my feces is sludge consistency. Nausea accompanies. Cholecystectomy 1995. Advice?
[|AI|]  Hi, Thanks for writing in. With history of colon cancer in family, there is a need to keep a close watch on bowel movements. Though sludgy stools for 2 weeks need not compulsorily be cancer, but it requires you to have an urgent colonoscopy and CT scan abdomen and pelvis with focus on the colon and rectum. It is possible that you might also have a bowel infection or an inflammatory bowel condition which is causing sludgy stools. It is also important to do complete blood investigations and tumor markers. Please also get blood test done to know if your blood counts are normal. Please do not worry.
