Hemorrhoids are not serious enough to turn into rectal cancer. Hemorrhoids and rectal cancer are two different types of diseases and there is no necessary connection between them. Hemorrhoids are usually caused by the downward displacement of the anal cushion and varicose hemorrhoidal veins, often accompanied by constipation. Rectal cancer is caused by malignant changes in the abnormally proliferating tissues in the intestinal tract, and is a malignant tumor that can also metastasize. Even if hemorrhoids develop to a more serious degree, they will not turn into rectal cancer. However, hemorrhoids and rectal cancer are both lesions that occur in the anal area, and there are some similarities in symptoms, which need to be identified by going to a regular hospital and completing the relevant examinations, such as colonoscopy, anal diagnosis, anoscopy and so on. In the specific diagnosis of the disease, it is recommended to combine the actual symptoms of the patient, the examination report and the analysis and judgment of professional doctors to clarify the specific disease and then treat it as soon as possible.
