There is a problem with intestinal 8mm subtypical polyps, but the severity of the problem depends on the pathological type and size of the polyp, for example, half of the adenomatous polyps larger than 2cm will become cancerous. Intestinal polyp is a disease located in the intestinal mucosa, and there are various types of pathology, such as adenomatous polyp, inflammatory polyp, hyperplastic polyp, and so on. Adenomatous polyps occur mostly in adults, preferably in the sigmoid colon or rectum, and the risk of cancer is high. About half of the patients with polyps larger than 2cm in diameter will have cancerous polyps. Inflammatory polyps are caused by inflammation and can be secondary to a variety of diseases, such as amoebic colitis, etc. Generally, inflammatory polyps usually do not become malignant, and the main treatment is the treatment of the primary disease. Hyperplastic polyps are the most common polyps, non-tumorigenic, with little possibility of cancer, and the main treatment is surgical resection under enteroscopic conditions. Intestinal 8mm subtypical polyps should seek medical attention in time, usually under the condition of colonoscopy resection and routine biopsy.
