A member asked:

Hi doctors. my stool appeared blackish, but when i wiped it was yellow. i had a colonoscopy last october 2020 which showed diverticulosis but no colon cancer. could colon cancer develop in that time?

A doctor has provided 1 answer

Black stools are seen with upper GI bleeding (coming from the stomach) but would not clear so quickly. Certain foods and medicines can cause black stools (eg. iron, Pepto-Bismol). Colon cancer would not develop in 1 year.
