Intestinal polyp disease itself will not affect the survival time of patients, but there is a certain possibility of cancer, which can affect the life expectancy of patients, but the specific life expectancy is related to the severity of the patient’s condition. However, if malignant changes occur, it will have an impact on the patient’s life expectancy, and the exact length of life is related to the condition. Intestinal polyps, also known as bulging lesions of the intestinal mucosa, are benign diseases, and it is recommended to treat them actively and effectively at an early stage, such as smaller, isolated intestinal polyps, by colonoscopy-guided ligation and electrodesiccation. In case of multiple, familially inherited intestinal polyps, their malignant potential is relatively high and they should be promptly treated by partial bowel resection. With aggressive treatment, the survival time is usually not affected in general. However, if it is not treated, it has a higher chance of easily becoming malignant to cancer in 5-10 years. The specific survival time is related to the stage of intestinal cancer and treatment methods, and the active treatment usually has a 5-year survival rate of 99% for stage I, and 87%, 67% and 10% for stage II, III and IV respectively. Patients with intestinal polyps should pay attention to their diet and avoid eating too much stimulating food, and should focus on light and nutritious diet.
