The differences between hemorrhoids and rectal cancer are as follows: 1. Rectal cancer is a tumor, a malignant tumor. Rectal cancer is more harmful and has a great impact on the prognosis of the patient. Hemorrhoids are benign diseases, benign diseases are relatively less harmful to patients, and hemorrhoids are completely curable; rectal cancer can be cured if the treatment is standardized in the early stage, if it is found late, to late stage rectal cancer, it is more difficult to be completely cured, which has a greater impact on the life of the patient; 2. Hemorrhoids can often have blood in the stool, have pain around the anus, are vascular hemorrhoid mass, vascular mass gathered on both sides of the dentate line, there are internal and external hemorrhoids The hemorrhoids can be treated by a doctor who specializes in hemorrhoids and fistulas to solve these problems. However, rectal cancer is often above the dentate line and can originate from adenocarcinoma, or if it is on the edge of the dentate line, it can be squamous cancer. If rectal cancer is found late, it can be more dangerous to the prognosis and to a person’s life and health, so it is important to pay high attention to rectal cancer.
