What is the biggest difference between internal hemorrhoids and rectal cancer

The differences between internal hemorrhoids and rectal cancer are generally reflected in the causes, symptoms, diagnosis, treatment, prognosis, etc. It is recommended to go to a regular hospital for relevant distinction.

1. Causes: Internal hemorrhoids are caused by congestion, swelling or prolapse of the vascular cushions (hemorrhoids) in the anal canal. Common causes include long-term constipation, diarrhea, long-term sitting, pregnancy, obesity and genetic factors. Rectal cancer is a malignant tumor that usually develops from abnormal proliferation of cells in the lining of the rectum. Risk factors include age, family history, poor eating habits, obesity, smoking, excessive drinking and certain genetic diseases.

2. Symptoms: Common symptoms of internal hemorrhoids include blood in the stool (usually bright red blood), anal discomfort, anal itching, and sometimes hemorrhoid prolapse. Rectal cancer symptoms may include blood in the stool (may be dark red or black), changes in bowel habits (such as constipation or diarrhea), abdominal pain, weight loss, fatigue, and a feeling of a mass in the rectum.

3. Diagnosis: Internal hemorrhoids are usually diagnosed through anal examination (such as digital anal examination) and anoscopy (such as anoscopy or proctoscopy). Rectal cancer needs to be confirmed through endoscopy (such as colonoscopy), imaging examination (such as CT scan or MRI) and tissue biopsy.

4. Treatment: Treatments for internal hemorrhoids include medication, rubber band ligation, injection sclerotherapy, laser therapy, or surgical removal. Treatments for rectal cancer may include surgical removal of the tumor, radiation therapy, chemotherapy, or targeted therapy, depending on the stage of the cancer and the patient's overall health.

5. Prognosis: Internal hemorrhoids usually have a good prognosis and can be controlled with non-surgical treatment in most cases. The prognosis of rectal cancer depends on the stage of the cancer, the response to treatment, and the patient's overall health. Early diagnosis and treatment usually have a better prognosis.

It is important to seek medical attention promptly for evaluation and diagnosis if blood in the stool, changes in bowel habits, or other concerning symptoms occur to rule out serious conditions such as rectal cancer.
