    How to distinguish rectal cancer from hemorrhoids

    Early rectal cancer is easily mixed with hemorrhoids, and how to distinguish it is very important. First of all, hemorrhoids will not cause difficulty in defecation, especially thin stools. Even if the hemorrhoids are incarcerated, they are only manifested as short-term painful defecation and unwillingness to relieve the stool; once the edema and inflammation subsides, return to normal immediately; on the contrary, Patients with rectal cancer have difficulty in defecation at an early stage, the stool becomes thin, accompanied by abdominal swelling, paroxysmal abdominal pain, and sometimes bowel sounds. The symptoms generally do not resolve spontaneously, but often worsen. Both rectal cancer and hemorrhoids may have blood in the stool, but the former blood and stool are often mixed together, causing more bleeding. Hemorrhoids bleeding usually occurs before or after the stool, and the amount of bleeding is small, showing blood attached to the surface of the stool. The mass of patients with rectal cancer will not shrink, but will only gradually grow. Its shape is cauliflower-like, light red, and easy to bleed when touched; while the mass of hemorrhoid edema is often smooth, dark red or dark purple, and it is not easy to bleed. Finally, the late stage of rectal cancer sometimes shows corresponding symptoms because the tumor invades the surrounding tissues. For example, the invasion of the bladder can cause painful and frequent urination, the invasion of the presacral nerve can cause severe and continuous pain, and the liver can cause hepatomegaly and jaundice. , And there are phenomena such as anemia.
