[|Human|] Ive noticed black spots in my stool for the past 2 days and on two occasions red streaks on a single piece of stool. Iam very concerned since Ive been having irregularity My docter diagnosed me with diverticulosis but he never schedualed a colonscopy and Im afraid it could be colon cancer.
[|AI|]  Altered bowel habits (irregularity) and blood in stools should be investigated. Possibility can be an inflammation mass secondary to diverticulitis causing obstructive symptoms and alteration in bowel habits, but a high index of suspicion should be kept for colon cancer. I would suggest routine lab tests and an ultrasound scan of abdomen and pelvis to be followed by a CAT scan if required. If no inflammatory mass is seen then a colonoscopy can be planned. Please discuss it with your doctor.
