Is blood in the stool a sign of colon cancer?

Blood in the stool after defecation is not necessarily colorectal cancer. The cause of this symptom is related to various factors such as inflammation, hemorrhoids, and tumors. It is necessary to find out the cause immediately and then carry out targeted treatment.

Blood in the stool after defecation is a common symptom, indicating bleeding in the colon and rectum, which causes blood in the stool, resulting in blood in the stool. However, the causes of blood in the stool after defecation are more complicated. Some patients are caused by inflammation, such as inflammatory bowel disease, nonspecific inflammatory bowel disease, etc., which will affect the quality of stool and produce varying degrees of bleeding. Some patients have bleeding in the stool due to hemorrhoids, and are prone to bleeding after defecation, especially when constipated. In severe cases, there may be protruding lumps.

Tumors are also an important cause of bloody stools, mainly including colorectal cancer or precancerous lesions, which can cause intestinal damage, affect bowel movements, and produce varying degrees of bleeding in the stool. For post-defecation bleeding caused by colorectal cancer, drugs such as bevacizumab and cetuximab can be used for treatment. In severe cases, endoscopic submucosal dissection and surgical treatment should be performed according to the condition, with regular follow-up after surgery and targeted nursing work.
