What are the symptoms of sigmoid colon polyps?

Sigmoid colon polyps affect many people, and in fact, these diseases also have the possibility of becoming cancerous. Therefore, in order to reduce the harm and the threat to health, they must be discovered and resolved in a timely manner. For example, you must be vigilant about blood in the stool, changes in bowel habits, and abnormal stools.

1. Colon polyps refer to growths that protrude from the colon mucosal epidermis into the cavity. Colon polyps mostly occur in the sigmoid colon and rectum, more often in men than in women, and the incidence rate increases with age. The canceration rate of colon polyps is related to the tissue type, size and epithelial dysplasia of the polyps. Generally speaking, the canceration rate of adenomatous polyps is relatively high, among which the canceration rate of papillary adenoma is 30%~70%. The larger the adenoma, the higher the canceration rate. If the diameter is greater than 2 cm, the canceration rate reaches 30%~50%. The canceration rate of severe dysplasia is 27%, and it is estimated that the time it takes to become cancerous is 5 to 15 years.

2. Colon polyps basically have no obvious symptoms, but if symptoms such as blood, changes in bowel habits, abnormal stool shape, etc. occur, you need to go to a regular hospital for diagnosis and treatment in time.

3. Bloody stool is the most common symptom in patients with colon polyps. However, many people mistake bloody stools as a symptom of hemorrhoids, resulting in the best time for treatment being missed. There is a fundamental difference between the bleeding caused by hemorrhoids and colon polyps.

4. Bleeding caused by hemorrhoids often manifests as blood dripping after defecation, which is bright red. Bleeding caused by colon polyps is often mixed with stool and is bright red or dark red. It is mostly caused by ulceration of the surface of polyps.

5. In addition, changes in bowel habits, such as changes in bowel movement time and frequency, as well as constipation or unexplained diarrhea, especially when constipation and diarrhea occur alternately, or abdominal pain occurs, should be a cause for concern.

6. It should be noted that if the stool shape is abnormal, you should pay attention to it. Normal stool should be cylindrical, but if the polyp is large and compresses the stool in the colon cavity, it will often become thinner or flat when discharged, sometimes with blood stains. If the patient experiences any of the above three symptoms, he or she must not be careless and should go to a regular hospital for treatment in time.

7. Healthy adults over 50 years old should undergo a colonoscopy if conditions permit. Patients with a family history of colorectal polyps, colon cancer, diarrhea, constipation, or bloody stools, and whose physical examinations reveal elevated blood CEA and CA199, and positive fecal occult blood, should undergo screening for colon lesions, with colonoscopy being the preferred method. Regardless of the type of colon polyp, a biopsy should be taken under endoscopy and sent for pathological examination. Patients who cannot or do not want to undergo colonoscopy can choose barium enema or CT virtual colonoscopy.
