Causes and nature of lesions: rectal cancer is a malignant tumor occurring in the rectal region, the causes of which are related to hereditary factors, exposure to toxic substances, radioactive substances, daily dietary habits and intestinal inflammation, etc. Hemorrhoids is a benign lesion occurring in the anal canal region, the causes of which are related to hereditary factors, daily dietary habits and increased pressure in the abdominal cavity. 2. Clinical symptoms: Rectal cancer patients’ clinical symptoms mainly focus on digestive system symptoms (abdominal pain, abdominal distension, indigestion, increased frequency of stools, bloody stools, mucus stools, etc.), systemic symptoms (fatigue, low fever, weight loss), etc.; hemorrhoids patients’ symptoms such as bleeding, anal itching, pain, protruding anal lumps, etc. are common. 3. Different treatment plans: after diagnosis of rectal cancer, patients are usually treated mainly by surgery, and then combined with radiotherapy, targeted drug therapy and other measures to stabilize the condition and prolong the survival time of patients as much as possible. Patients with hemorrhoids are mainly treated conservatively, through anally entering hemorrhoid cream, hemorrhoid suppository and other medicines under doctor’s guidance, combining with diet and defecation habit adjustment, so as to stabilize the condition. For patients with complicated condition, surgical treatment is available to cure the lesion completely.
