This is one of the most common patient confusions we encounter during medical treatment. The reason why these two diseases are often compared by people is that they have "three similarities": similar parts, similar performance, and similar prone groups-both of them occur at the end of the intestine close to the anus. Bleeding and changes in bowel sensation related to defecation are more common among middle-aged and elderly people. The way to distinguish these two diseases seems to be a commonplace talk. Here I would like to emphasize three points:
1. Hemorrhoids will not become rectal cancer: As we said in "What is internal hemorrhoids", the essence of hemorrhoids is the aging of the normal anal cushion structure, while rectal cancer is the malignant transformation of the intestinal mucosa and abnormal tumor tissues. The two diseases are fundamentally different and will not transform into each other. Many patients request hemorrhoid surgery because they are afraid of rectal cancer. They think that treatment of hemorrhoids can reduce the risk of rectal cancer. This is a misunderstanding.
2. Rectal cancer often coexists with hemorrhoids: Because the incidence of hemorrhoids is too high, most patients with rectal cancer have hemorrhoids at the same time. The reason why it is difficult to distinguish patients from the symptoms, except for the high similarity of the symptoms of the two diseases, often It is because he does have clinical manifestations of these two diseases at the same time. This is the first reason why I personally do not believe that patients can infer rectal cancer based on various symptoms.
3. The diagnosis and treatment of hemorrhoids and rectal cancer are completely different: hemorrhoids are chronic and non-fatal diseases, and the main harm is to cause various discomforts and inconveniences to patients. Therefore, the principle of diagnosis and treatment is to solve the symptoms with the least cost. See me for treatment again.” Rectal cancer is a fast-progressing and fatal malignant tumor, and it always has a long-term asymptomatic precancerous state. If it can be found at this stage, a small operation can be completely cured. Therefore, its principle is evidence-based positive examination and treatment. In layman’s terms, “I’m looking for a disease to treat”, and the tumor at this stage does not have any clinical manifestations. This is because I personally do not recommend that patients infer whether they are based on various symptoms. The second cause of rectal cancer.
