People should pay attention to the symptoms of colorectal cancer. Many people are in danger of their lives because they don't know the symptoms of colorectal cancer. So what are the specific symptoms of colorectal cancer ? Let the experts answer these questions for us. I hope that reading this article will be helpful to you.

What are the symptoms of colorectal cancer? The color of blood in the stool depends first on the height of the bleeding site. When bleeding occurs in the upper digestive tract such as the esophagus, stomach, duodenum, as well as the liver, bile duct, and pancreas, the stool is mostly brown or tarry. When bleeding occurs in the lower digestive tract such as the small intestine, colon, rectum, and anal canal, the stool is mostly dark red or bright red. However, the color of blood in the stool is also related to the amount of bleeding and the speed of discharge. When acute upper gastrointestinal bleeding is accompanied by increased intestinal peristalsis. And small intestinal bleeding, if it stays in the intestine for a long time, tarry black stools can also be discharged.

Hemorrhoids are especially rare in elderly men. Painless intermittent fresh blood after defecation is a rare symptom of internal hemorrhoids in the early stage. The most common causes of blood in the stool are: Hemorrhoids. There is a saying among the people that "nine out of ten people have hemorrhoids". Because feces rub the hemorrhoidal mucosa, there will be blood dripping in the stool or blood on toilet paper. A few bleed in the form of jets, which can stop on their own.

The symptoms of colorectal cancer are mostly intermittent and the amount of bleeding is small. Colorectal polyps have the possibility of becoming cancerous. The blood in the stool caused by colorectal polyps is similar to hemorrhoids. Therefore, they should not be ignored.

What are the symptoms of colorectal cancer? A small amount of blood is often seen on the surface of the stool or toilet paper during defecation. Anal fissures can also cause bloody stools or dripping blood, but anal fissures often have typical manifestations, namely pain around the anus, constipation and bleeding, and the pain is more severe and periodic.

Ulcerative colitis Ulcerative colitis often causes chronic diarrhea. The stool is mucous, purulent and bloody, accompanied by abdominal pain and fever. The diagnosis can be confirmed by fiber colonoscopy. The incidence of colorectal cancer in patients with ulcerative colitis is 510 times that of the normal population, and the malignancy level is high. Therefore, early diagnosis and early treatment are also required. The key is to detect the symptoms of colorectal cancer early.

Food poisoning, bacterial dysentery, amoebic dysentery, blood disease, vitamin C and K deficiency, epidemic hemorrhagic fever, allergic purpura, intussusception in children, etc. can also cause blood in the stool. Blood in the stool is often a signal of many diseases. In short, it includes the digestive system and the whole body.

It is extremely harmful to people, so any form of blood in the stool should be treated as soon as possible. Perhaps a simple "digital rectal examination" can make a clear diagnosis, and surgical treatment can be performed as soon as possible to save precious lives.
