The difference between hemorrhoids bleeding and colorectal cancer, first of all, hemorrhoid bleeding is often bright red, and generally is not mixed with stool, such as blood on paper, blood droplets, and in severe cases, gushing bleeding which may cause symptoms of anemia, and it is not significantly related to stool, meaning it is not very mixed. However, sometimes, bleeding caused by irritating hemorrhoids during defecation might be slightly mixed, but generally, it is not. As for colorectal cancer, if bleeding occurs, it is often in the later stages and the blood is usually dark red or purple-red, generally not in large amounts, and it is often mixed with stool. You might also see mucus and pus. Therefore, if there is bleeding, we recommend promptly undergoing a colonoscopy to avoid missing a diagnosis of colorectal cancer.
