Bowel polyps are not tumors, but they have the potential to develop into tumors. Generally speaking, the cancer rate of single polyps is low, but as the patient’s age increases and the number of polyps increases, the cancer rate gradually increases. Bowel polyps are divided into inflammatory bowel polyps and adenomatous bowel polyps. Inflammatory bowel polyps can disappear after the inflammation is cured. Adenomatous intestinal polyps generally do not disappear and are divided into tubular adenomatous intestinal polyps, villous adenomatous intestinal polyps and mixed intestinal polyps, of which villous adenomatous intestinal polyps have the highest rate of cancer, which can reach 50% or more, while tubular adenomatous has the lowest rate of cancer at 5%-10%, and mixed intestinal polyps are in between.
