There are many types of abdominal masses and the shape of the mass varies depending on the location where it occurs. Generally benign masses are round or oval, with clear boundaries, mild pain or no pain when touching the mass, and very good mobility when pushing the mass. If the mass is caused by malignant tumor, the boundary of the mass is usually unclear, there is obvious pain when pressing the mass, and even the mass is more fixed when pushing the mass. If there is a mass in the abdomen, it is necessary to come to the hospital for examination in time to avoid delaying the disease due to malignant tumor, and to decide the surgical treatment plan after clarifying in what part the mass is caused. In case of small intestine mesenchymal tumor, partial resection of small intestine is needed; in case of colon cancer, radical treatment of colon cancer is needed.
