Bleeding in the stool is one of the common symptoms in daily life and often causes concern. However, many diseases can cause blood in the stool, which is mainly divided into benign diseases and malignant tumors. Among them, hemorrhoids are the most common benign disease that causes blood in the stool, while rectal cancer is the most common type of malignant tumor. However, people often attribute blood in the stool to a fire or hemorrhoid flare-up, ignoring other possible conditions.
Hemorrhoids are characterized by fresh blood, usually dripping or spurting blood when the patient holds his breath before defecation, which is mainly due to the fact that the hemorrhoidal vascular mass is very close to the ** mouth, or even at the ** mouth, so it is susceptible to squeezing and rupture. Hemorrhoidal bleeding is characterized by dripping or spraying of blood, separation of blood in the stool. After defecation, the sphincter reflexively contracts and drip blood again, and the blood is excreted step by step with the stool.
In rectal cancer, hematochezia is characterized by mucus, dark red blood in the stool, and blood in the stool is mixed. Bleeding from rectal cancer is generally chronic bleeding from tumors in the lumen of the rectum, so in most cases it does not spray or drip out like hemorrhoids, but is mixed in the stool. Rectal cancer is bleeding dark red instead of bright red, and there is an increase in inflammatory exudate on the surface of the tumor, forming mucus. Therefore, hematochezia in rectal cancer is characterized by dark red blood in the stool with mucus, mixed with blood in the stool.
After understanding the characteristics of bleeding in the stool for hemorrhoids and rectal cancer, we can find the difference between them. If there are symptoms of blood in the stool, do not ignore it easily, and you should seek medical examination in time for early detection and possible diseases.
