The hemorrhoids will not become cancerous if they bleed for a long time, but hemorrhoids and cancer are two different diseases. Hemorrhoids are mostly caused by varicose veins and downward migration of the anal cushion, and have many causes, among which constipation, long-term alcohol consumption, eating a lot of irritating food and being sedentary are the main triggers. The etiology of anorectal cancers such as intestinal tumors and rectal cancer is not exact at this time, but these diseases can also show symptoms of long-term bleeding, leading many patients to mistakenly believe that hemorrhoids have become cancerous over time, but there is no necessary causal relationship between the two. Although long-term bleeding hemorrhoids are not cancerous, they do require active treatment. If left undiagnosed, they can lead to anemia due to blood in the stool, which can lead to a decline in a person’s organism, and in severe cases, symptoms such as coma and shock, which are also detrimental to subsequent surgical treatment. Patients with hemorrhoids should pay attention to their diet, avoid alcohol and spicy stimulating foods, increase the intake of fibrous foods, drink more water, change bad bowel habits, keep the bowels open, take laxatives if necessary, avoid sitting for long periods of time, and exercise properly.
