The colon is one of the organs responsible for digestion, also known as the tubular gland. The colon and rectum cooperate with each other to fully digest the food taken by the body to obtain the necessary energy for the body, but the colon is very prone to colonic tubular glands. Tumor, once it is sick, may affect the life of the patient, then, is the colonic tubular adenoma serious, will it be cancer?

　　 1. Symptom introduction: Tubular adenoma of the colon is a common malignant tumor in the gastrointestinal tract. It is colon cancer, which is second only to gastric and esophageal cancer, and is the most common part of colorectal cancer.

　　According to clinical observation, it was found that a part of intestinal cancer occurred on the basis of rectal polyps or schistosomiasis; chronic inflammation of the intestine, some can induce cancer; high-fat high-protein diet caused increased secretion of bile acid, after People are broken down into unsaturated polycyclic hydrocarbons by intestinal anaerobic bacteria, which can also cause cancer.

　　 2. Severity: The quality of life of postoperative bowel cancer is significantly reduced, including: decreased sexual function, excretory function, increased psychological barriers and reduced social activity; colorectal cancer is so common, but most patients are found when It is already late, and the best opportunity for treatment has been lost, resulting in a low 5-year survival rate of patients with colorectal cancer after diagnosis. In China, 1 person dies of colorectal cancer every 5 minutes.

　　 3. Symptoms: The clinical features of early bowel cancer are mainly blood in the stool and changes in bowel habits. When the cancer is limited to the rectal mucosa, the blood in the stool is the only early symptom accounting for 85％ The patient valued it. At that time, an anal finger examination was performed, and most of them could touch the mass. In addition to the common systemic symptoms such as loss of appetite, weight loss, and anemia, patients with intermediate and advanced bowel cancer also had an increase in the number of bowel movements, endless bowel movements, frequent bowel movements, and rapid and rapid cancer. Local irritation symptoms. Increased cancer can cause bowel stenosis and signs of intestinal obstruction.

　　Intestinal cancer often invades surrounding tissues and organs, such as bladder and prostate and other adjacent tissues, resulting in frequent urination, urgency, and difficulty urinating. Invaded the anterior sacral nerve plexus, with pain in the sacral tail and lower back. Rectal cancer can also metastasize to the liver, causing hepatomegaly, ascites, jaundice, and even cachexia.

　　 Colon tumors are easily misdiagnosed. When the number of stools in the early period increases, and the stool has mucus and pus blood, it is easy to be misdiagnosed as diseases such as dysentery, enteritis or hemorrhoids, thus losing the opportunity of early radical treatment for resection.
