Correctly understand blood in the stool caused by rectal cancer

Intestinal cancer is a common digestive tract tumor disease. Many patients with rectal cancer cannot clearly identify it in the early stages of the disease. Since the symptoms of rectal cancer are diverse and not single, it is easy to ignore the symptoms of rectal cancer, delaying diagnosis and treatment. Although blood in the stool is a typical symptom of rectal cancer, many patients confuse it with diseases such as enteritis or hemorrhoids.

Therefore, we must recognize the difference between blood in the stool caused by rectal cancer and the symptoms of other diseases, and accurately identify the disease. Dysentery generally has a history of acute onset, fever, tenesmus, and mainly pus and blood in the stool. Abdominal pain is relieved after defecation, and antibiotics are effective. Rectal cancer does not have the above-mentioned typical symptoms, and the feeling of anal prolapse does not ease after defecation, and antibiotics are ineffective. Hemorrhoids have constipation or bleeding in the stool. The bleeding is bright red and attached to the surface of the stool or there are drops of blood after defecation. The blood in the stool of rectal cancer is caused by the ulceration of cancerous tissue. The blood is mostly dirty and has a fishy smell. When the rectal cancer is larger, it can narrow the intestinal cavity, and the stool is laborious and thin strips with edges and corners, which are not present in dysentery and hemorrhoids.

We hope that by understanding the characteristics of bloody stools caused by rectal cancer, we can help readers correctly identify the type of disease through this typical symptom of bloody stools and avoid the deterioration of colorectal cancer due to untimely detection.
