As a kind of “rich disease” related to high fat, high protein and low fiber diet, the incidence rate of colorectal cancer has increased significantly in recent years. At present, the incidence rate of colorectal cancer in all malignant tumors in Shanghai has risen from the 7th place in the last century to the 2nd place, and this trend is also the overall trend of the incidence rate of colorectal cancer in the eastern coastal areas with faster economic development. Bowel cancer can be treated and prevented, don’t take bowel cancer as hemorrhoids In fact, if colorectal cancer can be detected at an early stage and given standardized comprehensive treatment, the effect is very good. However, many patients confuse colorectal cancer and hemorrhoids, and treat colorectal cancer as hemorrhoids, and then find out that the disease has been in advanced stage; part of the patients who suffer from colorectal cancer are pessimistic, and lack of proper understanding of colorectal cancer; part of the patients can’t keep the anus and give up the treatment. What is hemorrhoid? Hemorrhoids are enlarged and shifted anal cushions. The so-called anal cushion is a ring-like spongy tissue band located on the dentate line, which is a normal tissue for every human being. When the normal fibroelastic structure of the anal cushion is destroyed with varicose veins in the anal cushion and chronic inflammation fibrosis makes its elasticity and retraction weakened after the anal cushion is congested and shifted down to form hemorrhoids. Hemorrhoids are benign lesions that can occur at any age, with the incidence increasing with age. The most typical manifestation of hemorrhoids is painless intermittent bleeding after defecation, and in a few severe cases, there may be jet bleeding, and prolonged bleeding may also cause anemia. However, pain is often the main reason for patients to seek medical attention. Pain occurs when complications such as hemorrhoid infection, ingrown hemorrhoids and thrombosis develop. Why are rectal cancer detected in many people who have been suffering from hemorrhoids for a long time? Rectal cancer is often misdiagnosed as hemorrhoids and treatment is delayed because there are no obvious symptoms in the early stage of rectal cancer, and the symptoms are very similar to those of hemorrhoids when it develops to a certain degree, both of which have intermittent blood in the stool and discomfort in the anus as the main symptoms. It is very difficult to identify hemorrhoids and rectal cancer only through clinical manifestations, therefore, the patients often confuse the two, which is also the reason why rectal cancer is easily misdiagnosed as hemorrhoids. This is also the reason why rectal cancer can be easily misdiagnosed as hemorrhoids. However, if patients go to the hospital at an early stage, they only need to be diagnosed through the rectal fingerprinting by professional anorectal surgeons. 80% of the misdiagnosed rectal cancer patients are not diagnosed because they do not go to the hospital to receive rectal fingerprinting by anal surgeons. Therefore, the majority of patients with blood in the stool and other anal symptoms must go to the hospital to receive anorectal surgeons to rule out colorectal cancer in order to feel at ease with the use of hemorrhoid drugs, once misdiagnosed, it is too late to regret! Can hemorrhoids become cancerous? Hemorrhoids is a benign lesion, while rectal cancer is a malignant disease, is the result of unlimited proliferation of epithelial tissue of the rectal mucosa, which occurs in the body of normal cells mutated into abnormal cells and proliferation, its growth is not controlled by the body’s own immune system, and can be invasive destruction of neighboring or distant tissues and organs. Therefore, benign hemorrhoids and malignant rectal cancer are fundamentally different in their pathogenesis, and their ultimate consequences are completely different. However, in the clinic we also see some hemorrhoids combined with rectal cancer patients, the two interact with each other to aggravate the symptoms, but scientifically speaking, hemorrhoids can not induce cancer.
