what does a hemorrhoids look like,Why is rectal cancer easily misdiagnosed

    There are many reasons for rectal cancer. Rectal cancer is a common malignant tumor in the gastrointestinal tract, second only to stomach and esophageal cancer, and is the most common part of colorectal cancer. Rectal cancer has a high chance of being misdiagnosed. There are several reasons why rectal cancer is easily misdiagnosed.

    1. Due to the absence of any symptoms in the early stage of rectal cancer, as well as people's poor knowledge of popular science and poor understanding of the disease, many people are not very vigilant towards rectal cancer, especially female patients and rural patients.

    2. Due to the limited quality, medical level and clinical experience of medical staff. The vast majority of patients repeatedly seek medical treatment in primary health centers. Due to the lack of basic knowledge about rectal cancer by some medical staff, they are insufficiently aware of the disease and pay insufficient attention to the disease; tumors are not treated as common diseases, especially for younger patients I was neglected and only thought of common diseases such as hemorrhoids and enteritis. I diagnosed it hastily, neglecting detailed understanding and comprehensive analysis of the medical history. I thought that hemorrhoids or indigestion would be caused by hemorrhoids or dyspepsia if I had a sticky stool. Furthermore, some doctors performed digital rectal examinations. Not paying attention to it, ignoring this examination, a few doctors failed to master the method of digital rectal examination.

    3. Application of antibiotics leads to prolonged misdiagnosis time. After antibiotics are applied to some patients, the inflammatory and edema around the cancer may be reduced, and the clinical symptoms may be temporarily relieved.

    The above is the reason why rectal cancer is easily misdiagnosed.

    In addition, experts specifically reminded that late-stage rectal cancer sometimes manifests corresponding symptoms because the tumor invades the surrounding tissues, such as invading the bladder can cause dysuria and frequent urination, invading the presacral nerve will cause severe and continuous pain, and metastasis to the liver may cause hepatomegaly Major symptoms, jaundice, and anemia. Therefore, even if patients with stool bleeding have hemorrhoids, they must be highly alert to the possibility of rectal cancer, and further examinations are necessary to rule out the possibility of cancer. We must pay attention to the application of digital rectal examination, proctoscope or sigmoidoscopy.
