Blood on the toilet paper after defecation is usually caused by local mucosal rupture, anal fissures, hemorrhoids, or similar conditions. The color of the blood can help assess the patient's condition: dark red blood warrants further evaluation with a colonoscopy, while bright red blood may indicate anal tear or hemorrhoids. However, bleeding from colorectal cancer is mostly continuous, whereas bleeding from anal fissures and hemorrhoids is typically intermittent.
