Multiple intestinal polyps have the potential to become cancerous, so it is necessary to consult a doctor in time and follow the doctor’s advice to control the condition in order to avoid deterioration. When there are more than three intestinal polyps, they are called multiple intestinal polyps. If left untreated, the polyps can cover the rectum and colon, and the polyps continue to grow and press on the surrounding tissues, which may cause intestinal obstruction or intestinal perforation, abdominal pain, diarrhea, and symptoms of bloody stools, which in turn increase the risk of cancerous changes. Patients should undergo regular colonoscopic biopsies to determine the nature of the polyp. If the polyp is inflammatory, it should be anti-inflammatory to avoid infection and recurrence; if it is familial or adenomatous, it should be treated with surgical resection to reduce the chance of cancer. If patients have multiple intestinal polyps, they should go to regular hospitals in time, under the guidance of doctors, to identify the causes and target treatment, so as to avoid deterioration and cancer.
