Intestinal tumors are classified into benign and malignant tumors. The severity is related to the size, site of occurrence, nature of the tumor, and how early it is detected, in addition to its own benignity and malignancy.
Generally speaking, benign tumors are relatively less severe, but if they are relatively large and grow in a bad location, they can also have serious complications such as intestinal hemorrhage, intestinal obstruction, and intestinal perforation. As for malignant tumor of intestine, the severity is generally correlated with its early or late detection, tumor classification and nature, growth site, invasion range, tumor size and so on. The earlier the detection, the smaller the tumor, the smaller the invasion, and the less malignant the tumor is, the less severe it is; conversely, the later the detection, the larger the tumor, the greater the invasion, and the more malignant the tumor is, the more severe it is.
In general, early surgery for intestinal tumors is very effective, with a five-year survival rate of more than 80 percent.
