There are some similarities between rectal cancer and hemorrhoids in terms of symptoms, which may include blood in stool, anal pain, anemia, etc. However, there are some differences in the symptoms of blood in stool between the two diseases, as follows: 1. Characteristics of blood in stool: For rectal cancer, blood in stool is usually fresh, dark red blood, and blood and stool are usually mixed together, while blood in stool for hemorrhoids is characterized by drops of bright red blood after forceful defecation, and blood and stool are usually separated. 2. 2. Specific signs: There are some symptoms that rectal cancer has but hemorrhoids usually do not, such as symptoms of intestinal irritation and changes in bowel habits, including constipation, diarrhea, abdominal pain, etc. There are also systemic symptoms such as intestinal obstruction, abdominal mass, emaciation, fever, general weakness, etc., which are also more common symptoms of rectal cancer, but rarely occur in hemorrhoids. Although there are great differences in symptoms between rectal cancer and hemorrhoids, sometimes it is difficult to assess whether it is rectal cancer or hemorrhoids based on symptoms alone, so it is necessary to improve physical examination and auxiliary examination under the guidance of professional doctors to make a clear diagnosis and exclude misdiagnosis and omission.
