1. Differential diagnosis from hemorrhoids: Hemorrhoids are common benign anorectal diseases. Their clinical manifestations are anal blood, which is bright red and generally not much. It is blood on toilet paper, blood dripping after defecation, blood in the cesspool, etc. The stool itself does not have blood, or only has a little blood. The blood is generally intermittent, mostly when the stool is dry or after eating spicy and irritating foods. It is not accompanied by abdominal pain or bloating. There is no thinning of the stool or change in stool characteristics (such as grooves in the stool). There is no obvious mass in rectal digital examination, and the finger cot is generally not stained with blood. On the contrary, rectal cancer is bloody in the stool, which is bright red or dark red, and generally bloody in every stool. When rectal cancer causes intestinal obstruction, there may be abdominal pain, bloating, etc. The stool can be deformed. In most cases, a mass can be touched during rectal digital examination, and the finger cot is often stained with blood. This is the diagnosis method of rectal cancer.

2. Differential diagnosis from rectal polyps: Rectal polyps may also cause blood in the stool, but generally do not cause abdominal pain, bloating, etc. Generally do not cause systemic symptoms (such as fatigue, weight loss). Rectal digital examination can touch a soft mass, and the finger cot can be stained with blood. Rectal cancer can cause symptoms of intestinal obstruction and systemic symptoms such as fatigue and weight loss. The diagnostic method of rectal cancer is to touch a hard mass, and the finger cot can be stained with blood.

3. Differential diagnosis from anal fissure: Anal fissure is anal blood, which is bright red and generally not much. Its characteristic is accompanied by severe anal pain during and after defecation. Anal skin fissures can be seen during anal inspection, and sometimes sentinel piles can be seen. The diagnosis method of rectal cancer is sometimes able to touch the hypertrophic anal papilla, and generally the finger cot does not stain with blood.
