Benign intestinal tumors should first be determined to be benign or not. It can be determined to be benign by colonoscopy without surgery, but precisely all lesions designated as benign by colonoscopy need to be removed. Most of them can be removed by colonoscopy, but there are some tumors that cannot be removed by colonoscopy, for example, they grow in the intestinal wall and cannot be removed, so it is sometimes difficult to determine the benignity and malignancy, and it is often necessary to remove them to determine them. There are also some tumors that are designated as benign preoperatively and can be completely left untreated unless they bleed or cause obstruction. If they are clearly benign, major surgery is not advocated. So the important thing is the diagnosis, because the diagnosis of the disease is divided into malignant and benign, so one has to be very careful and not to make the diagnosis easily. So the focus is more on the diagnosis and not on the treatment. If it is determined to be benign, it can be completely observed and does not require surgery.
