Bowel cancer is often dragged out by yourself for a long time, many people have simple stomach pain and abdominal pain in the early stage, but they don’t care much about it, just take some gastrointestinal medicine to stop the pain, in fact, this will only aggravate your gastrointestinal problems, then let’s see what are the manifestations of bowel cancer in the early stage. 1.Abdominal distension and abdominal pain Many people often have these two now because they are hungry and have stomach pain, and they think they are eating bad stomach, so they either eat a bit of gastrointestinal tablets or gastrointestinal medicine, thinking that it is solved, but in fact, it is not, or it is more serious. In fact, the real reason for abdominal pain and bloating is that your intestinal tract has been disordered for a long time, and also because of intestinal obstruction, which usually leads to vague abdominal pain, and if not treated in time, it will turn into intestinal cancer. 2.Blood in stool Because the lesion is closer to the anus, the blood color is mostly bright red or dark red, and the blood and stool are often separated. Only when the amount of bleeding is high, the stool will be brownish red and jam-like. There are such in patients with right hemicolectasis, and blood in the stool visible to the naked eye accounts for 36. 5%. This also belongs to the early symptom performance of colorectal cancer. 3.Anemia When the long-term chronic blood loss exceeds the compensatory function of hematopoiesis, the patient will have anemia, which is an early symptom of colorectal cancer. Tumor obstruction, when the tumor grows to a considerable size or infiltrates the muscle layer of intestinal wall, it can cause narrowing of intestinal canal, small intestinal lumen and obstruction of intestinal content. 4.Changes in stool habits and traits Patients with rectal cancer may have more frequent stools, but not much stool each time, or even no stool at all, only some mucus and blood are discharged. 5.Symptoms of bowel irritation Frequent bowel movement, diarrhea or constipation, sometimes alternating constipation and diarrhea, urgency, anal swelling, and often vague abdominal pain. 6.Intestinal obstructionIntestinal obstruction is common in left hemicolectomy. Ulcerative or hyperplastic type, colon cancer spreads around the intestinal wall and infiltrates to cause obstruction caused by narrowing of the intestinal lumen, often chronic incomplete mechanical intestinal obstruction, first appearing abdominal distension, abdominal discomfort, then appearing paroxysmal abdominal pain, hyperactive bowel sounds, constipation or thin stool (pencil-like, sheep stool-like) so that exhaustion and defecation stop.
