Hemorrhoids and bowel cancer have some differences in the color of blood in the stool, accompanying symptoms and systemic symptoms, but it is not possible to analyze and identify them by blood in the stool, and ultimately electronic colonoscopy is required for further accuracy. The color of blood in stool: hemorrhoids mostly bleed in bright red, and the blood and feces are separated, while the bleeding color of intestinal cancer is darker, usually in dark red, and the blood and feces are blended together. Accompanying Symptoms and Systemic Symptoms: Accompanying symptoms of hemorrhoidal bleeding are mainly localized anal symptoms, such as prolapse of anal mass, pain, or accompanied by constipation. As for intestinal cancerous diseases, in addition to different degrees of localized anal swelling and falling, and changes in the frequency of defecation, it will also be accompanied by systemic symptoms such as emaciation, fatigue, anemia, and so on. After the appearance of blood in the stool, if the proximal rectal bleeding is considered, anoscopy can be carried out to clarify whether it is bleeding hemorrhoids or anal fissure bleeding, and if it is suspected that there are intestinal tumors or intestinal inflammation caused by bleeding, it is recommended that the patient undergoes electronic enteroscopy, combined with the pathological examination under the enteroscopy in order to accurately diagnose. In conclusion, it is recommended that patients with blood in the stool must actively consult the anorectal department and complete the relevant examinations according to the doctor’s guidance and recommendations.
