Does defecate have no strength to get rectal cancer?

Hello: I'm glad to answer your question. Let me tell you about the harm of hemorrhoids. Do not rule out the possibility of rectal cancer, but first of all, you will definitely have symptoms of anemia. The main symptoms of hemorrhoids are hematochezia, pain, prolapse, increased local secretion and difficulty in defecation. The most important symptoms are hematochezia and prolapse. Repeated bleeding during defecation will cause a large loss of iron in the body and cause iron deficiency anemia. Iron deficiency anemia caused by hemorrhoids generally develops slowly and has no symptoms or mild symptoms in the early stage. When anemia is severe, there will be symptoms such as pallor, fatigue, loss of appetite, palpitation, accelerated heart rate and shortness of breath and edema after physical activity. Some patients have nervous system symptoms such as excitability, excitement and irritability. These symptoms can be eliminated by correcting anemia and treating hemorrhoids. Therefore, if hemorrhoids are found, they should be treated as soon as possible to avoid the above symptoms and complicate the treatment. Another main symptom of hemorrhoids is prolapse of internal hemorrhoids. Internal hemorrhoid protruding from anus is caught by sphincter, venous return is blocked, arterial blood is still continuously input, so that the volume of hemorrhoid nucleus is continuously increased until arterial blood vessels are compressed, thrombosis is formed, hemorrhoid nucleus becomes hard and painful, and it is difficult to send it back to anus. When the hemorrhoid nucleus prolapse cannot be sent back, it is called incarcerated hemorrhoid. Long-term incarceration of hemorrhoid nucleus can also cause the following pathological changes: necrosis: hemorrhoid nucleus protrudes out of anus, and eventually necrosis occurs due to local edema and ischemia. If necrosis spreads to the rectal wall, it will cause severe sepsis. Infection: Hemorrhoids will have different degrees of infection after incarceration. The patient developed symptoms such as acute diarrhea and obvious anal dilatation. At this time, the infection is mostly confined to the anus. If not handled properly, it is easy to cause the spread of infection and cause submucosal and perianal abscess. If the detached bacterial embolus ascends along the vein, coupled with improper use of antibiotics or no use of antibacterial drugs, portal vein bacteremia, even sepsis, and liver abscess can be formed. In short, hemorrhoids are harmful to the human body, but patients with hemorrhoids need not be too nervous. As long as it can be treated early and handled properly, the above serious complications can be avoided. I hope my answer is helpful to you. Please consult me again if you have any questions. Wish you good health.
