The difference between the symptoms of rectal polyps and rectal cancer

In the early stage, when the frequency of bowel movements increases and the stool contains mucus, pus and blood, it is easy to be misdiagnosed as dysentery, enteritis or hemorrhoids, thus losing the opportunity for early treatment. Therefore, when adults have abnormal bowel movements, they should be vigilant and undergo a proctoscopy or sigmoidoscopy if necessary. So, what is the difference between the symptoms of rectal polyps and rectal cancer?

Rectal polyps refer to the raised lesions on the surface of the rectal mucosa that protrude into the intestinal cavity, including adenomatous pediatric polyps, inflammatory polyps and polyposis. From a pathological point of view, their contents vary, some are benign tumors, and some are the result of inflammatory hyperplasia. However, because they look roughly similar to the naked eye, the vague name "polyp" has been used for a long time. The rectum is a common place for polyps, and because it is easy to find and treat, it is taken seriously. In recent years, it is believed that colorectal cancer originates from polyps. Early removal of polyps can reduce the incidence of cancer. Therefore, polyps are taken seriously as precancerous lesions.
Rectal cancer refers to cancer between the dentate line and the junction of the rectum and sigmoid colon. It is one of the most common malignant tumors in the digestive tract. Rectal cancer is located low and can be easily diagnosed by rectal examination and sigmoidoscopy. However, due to its deep location in the pelvic cavity and complex anatomical relationships, it is not easy to perform a thorough surgery, and the recurrence rate after surgery is high.
Rectal polyps may also cause blood in the stool, but generally do not cause abdominal pain, bloating, etc. Generally do not cause systemic symptoms. Rectal digital examination can touch a soft mass, and the finger cot may be stained with blood. Rectal cancer can cause symptoms of intestinal obstruction and systemic symptoms such as fatigue and weight loss. Rectal digital examination can touch a hard mass, and the finger cot may be stained with blood. I hope it helps you!
