When many people find that stool or blood after stool is considered hemorrhoids, there is actually another possibility: rectal cancer! Hemorrhage from hemorrhoids is very similar to that from rectal cancer, but there are some differences. For example, hemorrhoids usually bleed. For example, when the stool is dry, the bleeding is usually bleeding after defecation. Many patients describe the number of times anal bleeding may occur after defecation. The bleeding of rectal cancer may be a little red than hemorrhoids; Its blood may be in the stool and mixed with the blood in the stool.

Early rectal cancer and hemorrhoids have many similar symptoms, which directly delay the effective treatment of many patients. Rectal cancer is often mistaken for hemorrhoids, and the symptoms and characteristics of hemorrhoids: most of them are anal bleeding during defecation, mostly bright red, painless or intermittent pain, blood on the toilet paper, and most of them are aggravated after constipation, drinking or eating irritating food. Hemorrhoids, including internal hemorrhoids, external hemorrhoids and mixed hemorrhoids, are submucosa of the middle and lower rectum and anal mucosa.

By using pathological examination technology, both hemorrhoids and intestinal cancer showed foreign body hyperplasia. However, the pathological changes of hemorrhoids mainly lie in the limited local blood flow, which leads to the compression of veins and the formation of venous masses; "Ten people and nine hemorrhoids" vividly illustrates the universality of hemorrhoids. Hemorrhoids are mainly caused by eating habits and heredity. Although they are common, they are not malignant and are usually not difficult to treat.

Although hemorrhoids and rectal cancer are not at the same level in terms of disease nature and severity, both hemorrhoids and rectal cancer have symptoms of hematochezia and difficulty in defecation in the early stage, and the clinical misdiagnosis rate is still quite high. However, the bloody stool of hemorrhoids and rectal cancer is still slightly different. Patients with hemorrhoids are always worried about whether it will be "cancer". In this case, it is not a big problem to go to the hospital for anal examination and endoscopic examination. Followed by rectal cancer, rectal cancer is a common malignant tumor in the gastrointestinal tract, which mostly occurs in men over 40 years old. The early symptoms of rectal cancer are mainly asymptomatic or changes in bowel habits.
