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.
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.
